Verfahren zur Oberfläciienvergütung von Lei chtmetallbaubellenProcess for the surface treatment of Metal construction sites
Die Erfindung betrifft ein Verfahren ζ,ην Qberfläcfceiwergütung von Leichtrastallbauteilen, insbesondere von Leichtmetallkolben für Verbrenaungskraftiaasohinen im Bereich der Ringpartie, 'vorzugsweise im Bereich der kolfoenkr-onenseitigen Ringnute.The invention relates to a method "surface treatment" of lightweight structural components, in particular of light metal pistons for combustion engines in the area of the ring belt, preferably in the area of the ring groove on the kolfoenkr-on side.
Eb sind Verbremiiaigskraftraaschinen bekannt8 die entweder nach ihrer Auslegung oder nach dem Arbeitsort einen besonders hohen Verschleiß der Ringnuten, insbesondere der kolbenkronenseitigen Ringnute, mit Bruchgefahr der Kolbenringe befürchten lassen oder· zeigen. Anfälligkeit Iiiei-für besteht, wennEb combustion engines are known 8 which, either according to their design or according to the place of work, cause or show a particularly high wear of the ring grooves, in particular the ring grooves on the piston crown side, with the risk of breakage of the piston rings. Iiiei-for susceptibility exists when
a) aufgrund der konstruktiven Gecamtauslegung der ¥er-> brenmingskraftmascliine die Temperaturen im Ringfeld abnor-raal hoch liegen.a) due to the overall design of the ¥ erbrenmingskraftmascliine, the temperatures in the ring field are abnormally high.
b) extrem Rückstätids bildender Krr-iftstoff gefahren lird.b) extremely residue-forming fuel is at risk.
c) aus besonderen Gründen das Spiel des Kolbens groß gewählt wurde uod dadurch Kippbewegungen ermöglicht werden. c) for special reasons, the clearance of the piston has been chosen to be large and this enables tilting movements.

d) die Luftfilterung, besonders in staubreicher Umgebung, z.B. Baustellen, unzulänglich ist und nicht wesentlich verbessert werden kann.d) the air filtration, especially in a dusty environment, e.g. construction sites, is inadequate and not essential can be improved.
In allen diesen Fällen v/erden Kolbenringträger aus Grauguß oder Stahl verwendet, ctio mit dem Leichtmetallkolben vergossen und in die die Kolbenringnuten spanend eingearbeitet sind. Der Kolbenring liegt auf diese Art in verschleißfestem Material eingebettet und ist, gleichzeitig weniger hohen Temperaturen ausgesetzt.In all these cases, piston ring carriers made of gray cast iron are grounded or steel is used, ctio cast with the light metal piston and in which the piston ring grooves are machined. The piston ring is in this way in wear-resistant Material is embedded and is, at the same time, less exposed to high temperatures.
Oftmals werden auch Ringträger verwendet s um außergewöhnlich hohe Laufzeiten für den Kolben zn ermöglichen. Das ist dann sinnvoll, wenn bei allen übrigen, ebenfalls dem natürlichen Verschleiß unterworfenen wichtigen Triebwerksteilen ähnlich lange Zeiten zwischen den Überholungen liegen.Often, ring carriers are used to s exceptionally long lifetime for the piston zn allow. This makes sense if all other important engine parts, which are also subject to natural wear and tear, have a similarly long time between overhauls.
Die bekannteste Ringträgerbauart ist der zumeist aus einem hochlegierten, austi:r)itischf*n Sondergußeisen bestehende volle Ringträger, der einen gleichbleibenden vollen Querschnitt hat und der cöTn^ß den Erfordernissen wie Anzahl der aufzunehmenden Kolbenringe und Verankerung im Kolbenkörper ausgebildet ist. In groß'ü; Maß int der volle Ringträger über eine internetall:sehe Verbund schicht, die nach dem unter der Bezeichnung "ALF].N~Verfahr?n" "bekannten Verfahren erzeugt wird, mit dem Kolben verbunden (Bensinfccr \\r.-D. u. A. Meier: Kolben, Pleuel unä Kurbelwelle bei schneilaufenden Verbrennungsmotoren, 2. Aufl..» 3.11» Berlin/Göttingen/ Heidelberg 1961).The best-known type of ring carrier is the full ring carrier, usually made of a high-alloy, Austi: r) itischf * n special cast iron, which has a constant full cross-section and which is designed to meet the requirements such as the number of piston rings to be accommodated and anchoring in the piston body.

statt des vollen Ringträgers ein sogenannter aufgelöster Ringträger in den Kolben eingegossen ist» Da wegen seiner Biegeelastizität, hervorgerufen durch seine mäanderförisige Ausfiihrungsiorm, ein hoher Ausdehnungskoeffizient nicht mehr gefordert werden muß, kann als Material gewöhnlicher Stahl oder Grauguß verwendet werden» Der Kolbenring liegt im Betrieb sowohl auf den harten Flanken des Kolbenrings wie aber auch auf dem gut wärmeleitenden Kolbenwerkstoff auf (DT-PS 1 059 7129 DT-PS 1 042 956).Instead of the full ring carrier, a so-called dissolved ring carrier is cast into the piston. Because of its flexural elasticity, caused by its meandering design, a high coefficient of expansion is no longer required, ordinary steel or gray cast iron can be used as the material. The piston ring is both in operation on the hard flanks of the piston ring as well as on the piston material, which conducts heat well (DT-PS 1 059 712 9 DT-PS 1 042 956).
Bekannt ist auch ein Leichtmetallkolben, bei dem die in dem Kolben befindlichen Ringnuten mit Molybdän, Titan, Kobalt, Nickel oder deren Legierungen sowie rostfreiem Stahl in einer Einzel- oder Mehrfachschicht, in die die Ringnuten spanend eingearbeitet; werden, ausgefüllt sind (DT-OS 1 400 115).Also known is a light metal piston in which the annular grooves in the piston are coated with molybdenum, titanium, Cobalt, nickel or their alloys as well as stainless steel in a single or multiple layer in which the annular grooves incorporated by machining; are filled out (DT-OS 1 400 115).
Gegenüber dem vorgenannten Stand der Technik waren Gewichts- und Äufwandsgründe ausschlaggebend für die Entwicklung eines Verfahrens, mit dessen Hilfe der Verschleißangriff bei Leichtmetallteilen, vorzugsweise im Bereich der Ringpartie von Leichtmetallkolben, unter Verzicht auf die Verwendung von Ringträgern aus Sondereisenlegierungen auf ein Minimum gesenkt werden kann.Compared to the aforementioned prior art, weight and expense reasons were decisive for the development of a Process with the help of which wear attack on light metal parts, preferably in the area of the ring belt of light alloy pistons, dispensing with the use of ring carriers made of special iron alloys can be reduced to a minimum.
Nach der Erfindung wird das dadurch erreicht, daß mit dera Leichtmetallbauteil im Bereich der zu vergütenden Oberfläche ein festigkeitssteigernder und/oder verschleißfester Zusatzwerkstoff unter Zuhilfenahme von Ladung-strägerstrahlen wie Elektronen-, Plasma- oder Laserstrahlen unter Auflegieren desselben verschmolzen v.'ird. Anschließend wird das Leichtmetallbauteil einer an sich bekannten V/ärmebehandlung unterworfen. According to the invention this is achieved in that with dera Light metal component a strength-increasing and / or wear-resistant filler material in the area of the surface to be tempered with the aid of charge carrier beams such as Electron, plasma or laser beams with alloying of the same fused v.'ird. Then the light metal component subjected to a known heat treatment.

Durch diese Eigenschaften werden die Verschleißfestigkeit, die Warinhärte und die Warmfestigkeit des erfindungsgemäß behandelten Bereichs des Leichtmetallwerkstoffs, insbesondere Kolbenwerkstoffs, so wesentlich gesteigert, daß der verschleißenden als auch der verformenden Wirkung z.B. der Kolbenringe in den Ringnuten ein dem Ringträger vergleichbarer Widerstand entgegengesetzt wird. Hinzu kommt, daß keine Schweißeigenspannungen auftreten und damit Sprödbrüche vermieden werden.Through these properties, the wear resistance, the Warin hardness and the heat resistance of the invention treated area of the light metal material, in particular Piston material so significantly increased that the The wear and tear as well as the deforming effect, e.g. of the piston rings in the ring grooves, are comparable to the ring carrier Resistance is opposed. In addition, there are no residual welding stresses and thus brittle fractures be avoided.
Durch geeignete Wahl der Menge an Zusatzwerkstoff und Tiefe der Aufschmelzzone kann die Tiefe der Oberflächenvergütung in weiten Bereichen variiert werden.The depth of the surface finish can be determined by a suitable choice of the amount of filler material and the depth of the melting zone can be varied over a wide range.
