Abstract
The utility model discloses a wear resisitant piston ring which comprises an electroplated hard chromium layer at the outer circle surface of the piston ring. Al2O3 hard particles in the sizes of 2 to 10 microns are enchased in the reticulated pattern of the chromium layer. The abrasion of the wear resisitant piston ring is only the half of the ordinary hard chromium ring, and the wearable piston ring solves the problem that the ordinary hard chromium ring scuffs a cylinder easily in an engine. The wear resisitant piston ring has high wear resisitant and heat resistant load capacity, can meet the requirement of the high output and high discharge restriction of the modern automobile and is fit for various kinds of diesel engines and gasoline engines.
Description
One, technical field:
The utility model relates to a kind of piston ring, is specifically related to a kind of Wear-resitsting pistons ring.
Two, background technique:
At present, the surface of piston ring mostly is the durionise layer greatly, has certain wear resistance.Along with the rotating speed of motor car engine is more and more faster, output torque is increasing, more and more higher to the requirement of motor vehicle emission simultaneously, engine piston ring adopts the requirement of common hard chrome as the high output of cover coat incompatibility Hyundai Motor, maximum discharge restriction, is prone to problems such as scuffing of cylinder bore.
Three, summary of the invention:
Technical problem to be solved in the utility model provides a kind of requirement that adapts to the high output of Hyundai Motor, maximum discharge restriction, the Wear-resitsting pistons ring that heat-resisting load carrying capacity is high.
For solving the problems of the technologies described above, the technological scheme that Wear-resitsting pistons ring of the present utility model is adopted is such: it comprises the durionise layer on the piston ring excircle face, is inlaid with the Al that is of a size of 2～10 μ M in the reticulate pattern of said chromium layer
2O
3Hard particles.
The utility model has adopted and has been inlaid with Al
2O
3The composite chrome plating layer of hard particles, the platform experiment result who selects for use diesel engine, petrol engine, turbogenerator to carry out respectively with common hard chrome ring is: the utility model wearing and tearing have only half of common hard chrome ring, the wearing and tearing of cylinder sleeve a little more than common hard chrome ring, be the more important thing is that the heat load experiment shows its fabulous high-mechanic performance.Therefore, the utility model can adapt to the requirement of the high output of Hyundai Motor, maximum discharge restriction, and is not prone to problem such as scuffing of cylinder bore.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the utility model coating enlarges 1000 times structural drawing;
Fig. 3 is electroplated structural figure of the present utility model.
Five, embodiment:
Referring to Fig. 1, Fig. 2, Wear-resitsting pistons ring of the present utility model comprises piston ring matrix 1, and the durionise layer 2 on the periphery is inlaid with Al in the reticulate pattern 3 of chromium layer 2
2O
3Hard particles.
Referring to Fig. 3, process step of the present utility model is to adopt electrochemical method and the special electric mode of giving to deposit on unlike material (as KV1, KV4, F14, FC, ST etc.) piston ring excircle face.So-called specially is interpreted as for electric mode: in plating tank, alternately to be applied " positive current → reverse current → stop to " this mode of alternately giving electricity to electroplating piston ring.
Above-mentioned piston ring cover coat is chromium-pottery-coating (Chrom-Keramic-Schicht), is called for short CKS.The CKS technology is on the basis of existing electrolysis chromium plating, in the process of chromium deposition with Al
2O
3Hard particles is inlaid in the reticulate pattern 3.
1, scope: be used in the compound chromium layer of CKS36.
2, material: electrolysis chromium, aluminium oxide (AL
2O
3).
3, technology: electrochemical deposition.
4, technical characterstic: the abrasion resistance properties height, the equal wear extent of 1000km is the over half of common ring.Barrel wear is low, heat-resisting load carrying capacity height.
5, coating structure: inlaying aluminium oxide (AL in the chrome coating
2O
3) particulate.
6, AL
2O
3Particle size: 2～10 μ M.
7, microscopic crack density: 40～100/MM.
8, AL
2O
3The percent by volume of grain in chrome coating: 2～6%.
