Abstract
The invention discloses a nano composite titanium-aluminum-silicon nitride cutter coating and a preparation method thereof. The cutter matrix is WC / Co hard alloy, and the coating is a nano composite titanium-aluminum-silicon nitride coating containing a transition layer, wherein the coating contains titanium, aluminum, silicon and nitrogen elements; and the size of crystalline grains is 5 to 15 nanometers, the thickness of the coating is 1 to 4 microns, the micro hardness of the coating is 33Gpa, and the high-temperature stability reaches over 1,010 DEG C. A nano composite titanium-aluminum-silicon nitride coating cutter is a nano composite structural coating cutter prepared in a mode of combining ion plating and sputter-plating, and is suitable for cutting and processing high-hardness steel materials at a high speed.
Description
Technical field [0001] The invention relates to a nano-composite titanium-aluminum-silicon nitride tool coating coated by physical vapor deposition technology and a preparation method thereof. Background technique [0002] Tool coating technology better solves the contradiction between tool strength and toughness, and greatly improves tool durability and cutting speed. Since the advent of coated tools, tool coating technology has achieved rapid development, and there are more and more coating types. [0003] The early hard coating materials prepared by physical vapor deposition technology are usually simple TiN and TiC coatings with a microhardness of about HV 2300 and an application temperature of 500 to 600°C. They are relatively high-speed steel or hard alloy materials. It has high resistance to mechanical wear, anti-abrasive wear and low friction coefficient. At present, C, Al and other elements are added to TiN coatings to form multi-component multi-component coatings, such ...
