Abstract

The target of the study is to create a multi- component combined heat-resistant and wear-resistant coating of oxygen-, silicate- and carbide-containing substances (soluble oxides and silicates, insoluble oxides and carbides) on the grains of grinding powders by crystallization of soluble components from the solution in order to improve the performance of the tool.

The basic technology of layer-by-layer deposition (physical-chemical assembly) of combined heat-resistant and wear-resistant coatings on grinding powders (diamond, cBN, composite powders) has been developed.

The coating consists of oxygen- (B₂O₃, Al₂O₃, SiO₂, TiO₂, TiO, CaO, ZnO, CeO₂, SnO₂), silicate- (Na₂O(SiO₂)_n), K₂O(SiO₂)_n) and carbide- (SiC, TiC, B₄C) containing compounds in various combinations.

The heat resistance and technological properties of the investigated samples of grinding powders - initial and with applied coating - were determined.

The results of using abrasive powders with such combined coatings in a grinding tool are presented.
