METHOD OF MANUFACTURING SURFACE-COATED CUTTING TOOL WITH EXCELLENT ABRASION RESISTANCE |
摘要 |
A method of manufacturing a surface-coated cutting tool includes: forming an aluminum oxide layer having a layer thickness of 0.05 to 5μm and anα-alumina structure with a corundum type crystal structure on a cutting tool body using a sol-gel method. The step of forming includes adding an alcohol to aluminum alkoxide; adding an acid; stirring the mixture at 10° C. or lower to form a sol; applying the sol on a surface of the cutting tool body or an outer-most surface of a hard-coating layer formed on the surface of the cutting tool body; performing a drying process at least once, the applied sol being dried at 100 to 400° C. in the drying process; and annealing the cutting tool body with a dried sol layer at 500 to 1000° C.
