Application of additive technologies in manufacture of machine parts

Emerged in the late 1980s, the additive technologies are currently the advanced techniques of limited and piece production in different branches of machine building, medicine, aircraft and missilery. The additive technologies are the brand-new methods in manufacture of various articles, including metal items. The technologies can be used both to create a product and to treat a created piece, and the resultant material has the identical mechanical and physical characteristics as the products of conventional blacksmithing or foundry. The article describes two kinds of additive technologies using methods of layer formation. The problems connected with the required qualities and properties of parts are displayed. The methods to produce metal-particle materials from nickel for various branches of industry and machine building are presented. The implemented analysis marks the ways of improving strength of parts made of nickel powders. © 2018, Publishing house Mining book. All rights reserved.
