Improving the Quality and Durability of Restorative Coatings by Arc Deposition and Modification with Natural Additive Bentonite Clay

The study considers the possibility of improving the quality and service life of reducing coatings by arc deposition and modifying with natural additive bentonite clay. It has been established that when the modifier is introduced into the fluid bath during arc deposition, the phases and their interactions change. Introduction of the modifying additive bentonite clay significantly changes the crystalline lattice of the carbidephases. The optical-mathematical method revealed the absence of austenite and the pair interaction of ferrite-carbide during modification. The maximum proportion of phases corresponds to ferrite (33.8% -2 times decrease) and ferrite-austenite-carbide interaction (48.62% -2 times increase). The ferrite-austenite interaction increases almost 8 times during modification. The wear coefficient in this case is 2.2 times lower in comparison with the original steel 65Gand 1.4 times lower in relation to arc deposition with only T-620 electrode.
