Correlation between Properties of Oxide Compounds Formed on Contact Surfaces of Cutting Tools and Cutting Tool Wear Resistance

The article describes the influence of the acidity degree of oxide compounds formed on contact surfaces of carbide cutting tools type P on their wear resistance when cutting materials causing intensive diffusion wear. It was found out that when the acidity degree of surface film oxides formed on the cutting wedge contact surfaces decreases, wear resistance of cutting tools tends to grow.
