Abstract:
(EN) A diamond composite coating, a graded structure ultrafine hard alloy cutting tool with the diamond composite coating, and a method for manufacturing same. The alloy cutting tool comprises a cutting tool base body and the diamond composite coating. The cutting tool base body is provided with a normal organization layer, a cobalt-rich transition layer, and a cobalt-poor cube-rich phase layer. The diamond composite coating comprises a Ti-Al-Si-Cr alloy layer as a transition layer and a diamond layer as a functional layer. The cutting tool base body of the graded structure ultrafine hard alloy cutting tool with the diamond composite coating disclosed in the invention exhibits good adhesion to the diamond composite coating. The entire cutting tool has good resistance against abrasion and high temperature, high strength and excellent shock resistance. The diamond composite coating has good adhesion with the cutting tool base body, good layer-to-layer adhesion within the composite coating, and good resistance against high temperatures, corrosion, and abrasion.
(FR) L'invention concerne un revêtement composite de diamant, un outil de coupe en alliage dur ultrafin à structure étagée portant le revêtement composite de diamant, et leur procédé de fabrication. L'outil de coupe en alliage comprend un corps de base d'outil de coupe et le revêtement composite de diamant. Le corps de base d'outil de coupe est pourvu d'une couche d'organisation normale, d'une couche de transition riche en cobalt et d'une couche de phase riche en cubes et pauvre en cobalt. Le revêtement composite de diamant comprend une couche d'alliage de Ti-Al-Si-Cr en tant que couche de transition et une couche de diamant en tant que couche fonctionnelle. Le corps de base d'outil de coupe de l'outil de coupe en alliage dur ultrafin à structure étagée portant le revêtement composite de diamant selon l'invention présente une bonne adhérence au revêtement composite de diamant. L'ensemble de l'outil de coupe présente une bonne résistance à l'abrasion et aux températures élevées, une résistance élevée et une excellente résistance aux chocs. Le revêtement composite de diamant présente une bonne adhérence avec le corps de base d'outil de coupe, une bonne adhérence entre les couches à l'intérieur du revêtement composite et une bonne résistance aux températures élevées, à la corrosion et à l'abrasion.
