Physical And Mechanical Characteristics

A modern method of processing steel parts by ion-plasma sputtering in vacuum is proposed as a solution to the problem of friction and wear. An ion-plasma coating based on Ti-Cu has been developed. Such parameters as microhardness, roughness, friction coefficient of the intermetallic, conglomerate and nitride coatings have been studied

Two Parameters

Wear resistance of arc ion-plated chromium nitride films has been studied. It has been found that texture and phases composing the films depend much on bias voltage and nitrogen gas pressure at the deposition. A phase diagram was constructed as a function of these two parameters, which indicated that three categories exist: CrN single, CrN and Cr2N dual, and CrN and Cr dual phased regions, respectively. Results of Falex No. 2 test showed that the wear resistance of CrN single phased films is superior to others, especially when (220) preferred orientation is developed. Since hardness and surface morphology do not differ much between these films, a high toughness of CrN single phased film is considered to make a difference by suppressing abrasion wear.

Oxidation Technology

Comparative studies of the effect of discrete surface hardening by standard ion-plasma technology and discrete oxidation technology on wear resistance have been carried out. Metallographic studies have shown that discrete oxidation has a polycrystalline structure. It was found that the technology of discrete oxidation makes it possible to increase the hardness by 31% in relation to the uncoated material, and the wear resistance of the cutting tool with oxidation is 1.5-3 times higher than that of the tool hardened by the standard ion-plasma technology.

Formed Structure

Deposition of a titanium or a copper film onto the surface of commercially pure A7 aluminum and irradiation of the “film/substrate” system with an intense pulsed electron beam are carried out in a single vacuum cycle. Formation of a surface doped layer with a thickness of (20-30) μm is revealed. It is shown that the modified layer has a multiphase structure of a cellular rapid solidification of the submicron-nanosized range. Irradiation parameters are determined. It is established that the developed modification method allows forming a surface doped layer with the microhardness more than 4 times (Ti-Al alloy) or more than 3 times (Cu-Al alloy) greater than the microhardness of A7 aluminum; the wear resistance of the surface alloy Ti-Al exceeds the wear resistance of the initial aluminum in ≈2.4 times; doping of aluminum with copper is accompanied with an increase in the wear resistance of the material in ≈1.5 times.
