Investigation of the properties of coatings obtained by electric arc spraying

The paper considers possibilities to increase the wear resistance, corrosion and service life for parts of machines mechanisms via their hardening renovating using electric arc coatings characterized by high density, adhesion strength, micro hardness. Also, possibility controlling properties restored surfaces owing choice related equipment with required structure characteristics in order prolong machinery is shown. right spraying makes it possible speed temperature gas particles, reduce droplet diameter, density oxidation coatings. influence spray factors such as flow rate pressure working gases, composition combustion mixture, distance, dispersion spray, wire material, etc. on obtained has been investigated.
