Abstract
The present invention belongs to the field of surface metallurgy. It uses glow discharge and sputtering phenomenon in thin gas, sets auxiliary source around the workpiece, and at the same time uses vacuum arc discharge phenomenon, sets one or more cathode arc targets on the container wall as main metal source. Under the action of negative bias, the workpiece is heated to high temp. and bombarded and diffused by the metal ions to be diffused to obtain special physical, chemical and mechanical pure metal layer, alloy coating, compound coating and plating layer on its surface. The purposes of improving the metal infiltration speed and quality and optimizing the surface performance of the workpiece are achieved.
Description
The invention belongs to surface metallurgic and thermo-chemical treatment category.
The method of current plasma surface metallurgic is a lot, wherein double-layer metallic glow ion cementation and arc light ion metallic cementation are that the former the ion diffraction of state-of-the-art technology that develops rapidly is relatively good, can handle complicated shape and big area workpiece, but rate of ionization is low, infiltration rate is slow than the arc light ion metallic cementation.Though and the latter has the rate of ionization height, the strong point that infiltration rate is fast, it is poor to have ion diffraction, is difficult to realize the shortcomings such as processing of endoporus and complicated shape.The present invention is in order to overcome above-mentioned shortcoming, on the basis of metallic glow ion cementation technology, cathode arc source is set as the main supply source of desiring the metallic cementation element ion, and this novel surface metallurgy method is referred to as the arc-added glow ion implantation technique.
Characteristics of the present invention are the glow discharge utmost point sputtering phenomenons that utilize in the rarefied gas, auxiliary source electrode is set around processed workpiece, assistant metal source as infiltration element, utilize hollow cathode effect that itself and workpiece are heated up rapidly, desire metallic cementation atoms of elements or ion that auxiliary source electrode sputters out, under electric field action, bombard workpiece surface, thus it be heating source be again the auxiliary supply source of infiltration element.Utilize the electric discharge phenomena of vacuum arc simultaneously, one or more metallic cathode arc sources directly are set on wall of container, as the main source of desiring metallic cementation.Constantly generation high-energy, high-density, high-speed metal ion flow, under the effect of workpiece negative bias, quicken to arrive workpiece surface, all active atomic or ions that are sputtered onto workpiece surface rely on diffusion and ion bombardment strength to infiltrate workpiece surface or be deposited on workpiece surface, form pure metal layer, alloyed layer, plating key coat and compound cementation coating.

4Deng), its operating air pressure is 5 * 10
-1Change in the-50Pa scope.In container, be provided with negative electrode (9), under the driving of the rotating mechanism that is connected with substrate (7), rotate with certain speed, workpiece (13) is positioned on the cathode base, between negative electrode and anode (bonnet) (1), but connect a direct current voltage controller power source (6) (0-2000V), the usefulness metal auxiliary source electrode of infiltration element (10) that certain distance is arranged with workpiece is set around workpiece, between auxiliary source electrode and anode (bonnet), connect an adjustable power of direct current (5) (0-2000V), auxiliary source electrode plays heated parts and supplies with infiltration element.Between auxiliary source electrode and cathode base, but can be also equi-potential not of equi-potential.
It is one or more that metallic cathode arc source (3) is set on wall of container, between as anodic bonnet and cathode arc source, connect adjustable low-voltage and high-current direct supply (4) (0-100V, 0-200A) by after arc initiation device (2) striking, from metallic cathode arc source surface, launch high-energy, high-density, high-speed metal ion stream, bombardment processed workpiece surface, it is to desire metallic cementation ion master source, heating source, it also is bombardment purification source, workpiece is after being heated to high temperature under the acting in conjunction of auxiliary source electrode and arc source, desire the metallic cementation ion and infiltrate workpiece surface by means of ion bombardment and diffusion process, form uniform pure metal layer, plating bonded alloy layer.
For example: A
3Steel and 20 steel ooze Ti, Al, Ni, 1Cr through the arc-added glow ion
18Ni
9Unit such as Ti, W, Mo and Cr-Ni ooze or multiple permeation is handled, and workpiece temperature is 950 ℃ (temp measuring systems 12), and the treatment time is 30 minutes, and its infiltration layer all can reach more than the 100 μ m, and alloying element high-content in top layer can reach more than 80%.
Present technique can be made arc source target and auxiliary source electrode to the combination of the metallic element of any metallic element or metalloid element or its arbitrary proportion, infiltrate the top layer of any electro-conductive material, form pure metal, alloyed layer, plating key coat and compound cementation coating.Both can ooze, also can plate or the plating combination, be fit to the surface modification purpose that various materials or part require.
The present invention is provided with auxiliary source electrode as the second source of desiring the metallic cementation element, and it has good diffraction, and set cathode arc source is as the main source of desiring the metallic cementation element, though its diffraction is poor, ionization is from height, and metallics density is big, the energy height, and infiltration rate is fast.The arc spot that produces after the cathode arc source striking is chaotic simultaneously constantly moves at target material surface, because negative electrode water-cooled, be difficult for forming thin-skinnedization of metallic target and fusing like this, can settle in the bonnet optional position, adding workpiece at the uniform velocity rotates with cathode base, the synthesis result of above-mentioned feature makes this device can handle all kinds of parts of complex-shaped endoporus, concave surface and big area, obtains uniform cementation coating.As titanium, aluminium, chromium, nickel, tungsten, molybdenum, vanadium, niobium, tantalum etc., and different ratios between them, the alloyed layer of various combination or cementation coating and with the chemical combination cementation coating of carbon, nitrogen, oxygen.
