Fabrication of coatings and bulk products made of a nickel-based material by additive technology laser metal deposition

Resumo

It is shown that products made of a nickel-based material can be formed by direct additive laser deposition. Ring samples with good antifriction properties are formed. The material after direct laser deposition is characterized by a heterogeneous structure: coarse inclusions with a high hardness are distributed in a softer matrix. Final laser treatment leads to the formation of a homogeneous microstructure and the refinement of second phases.
