Many different methods of thermal spraying are used for deposition of coatings. The use of thermal spray technology in tribological applications is growing and will continue to grow. There is a need for a strategy or methodology for selecting a surface layer composition and structure and methods of their obtaining for a given tribological application. In this paper such a strategy is proposed and its elements are discussed.

Layer Composition

The simple isothermal problem is formulated to describe the composition of surface layer change during particle beam action. The finiteness of relaxation time for mass flux is taken into account. The analytical solutions for some limiting cases are presented. Numerical solution of total problem is carried out. It is shown that concentration distributions for reactants and for reaction product depend on relation between various physical scales.

Layer Composition

Hydrogen absorption leads to redistribution of the components of the surface layer of the amorphous alloy Fe73.8Si12.7B9.4Nb3.2Cu noncontact side, while the amorphous structure of this layer is preserved. The type of the micro-groups Fey Six changes in such a way that the ratio y: x decreases (to less than 1) and the chemical bond polarity decreases, as well. After degassing, the surface layer composition becomes similar to those before hydrogenation. The loss of the mechanical stability of the amorphous ribbon is accompanied by the formation of the micro-groups Fey Six with a decreased ratio of y: x.
