TERMS OF ELECTRODEPOSITION OF BRASS
Description
The article found that the corrosion rate of diffusion of brass alloys in an acidic environment reduced with increasing of zinc content in the coatings. High protec-tion can have 14 ÷ 20 at.% Zn
-
Description
The article shows the possible ways to control the quality of plasma coatings, such as modulation of the electrical parameters of indirect and remote arc plas-ma torch, vibration, thermal and electro-coating pro-cess, etc. Theoretically based on mathematical model-ing and experimental results of the effect of modula-tion of electrical parameters of the plasma deposition and hardening coatings on their quality are listed. We also developed new high-saving technologies and equipment for applying and hardening coatings on in-ner and outer compact surface on flat, cylindrical and shaped the surface of parts of friction pairs
