Abstract

The invention belongs to the technical field of cutters and particularly discloses a composite coating prepared on a circular saw blade through a physical vapor deposition method and a preparation method. The composite coating sequentially comprises a bottom layer, a buffer layer, a reinforcing layer and an abrasion-resisting layer from inside to outside. The bottom layer is a Ti metal layer, the buffer layer is a TiN layer, the reinforcing layer is a composite layer formed by alternately arranging a plurality of TiCN single layers and TiSiN single layers, the abrasion-resisting layer is a TiCSiN layer, and the buffer layer comprises a first TiN layer body and a second TiN layer body. The abrasion-resisting layer comprises the components, by mass, of 48%-56% of Ti, 30%-35% of C, 8%-12% of Si and 5%-10% of N. The composite coating is high in hardness, low in friction coefficient, good in high-temperature resistance, capable of meeting the high cutting speed, small in internal stress, high in strength and higher in bonding strength, and the preparation cost is lower by using a TiC alloy target, a TiSi alloy target and a TiCSi alloy target as target materials.

Description

technical field [0001] The invention belongs to the technical field of cutting tools, and in particular relates to a composite coating prepared on a circular saw blade by a physical vapor deposition method. Background technique [0002] Circular saw blades are cutting tools used for processing stone, wood, metal, plastic and other material blanks. The wear resistance, hardness, high temperature resistance and corrosion resistance of circular saw blades are important for the surface finish, precision and processing efficiency of cutting parts. Impact. High-speed steel circular saw blade is a saw blade containing a large amount of carbon, tungsten, molybdenum, vanadium and other elements. After heat treatment, it has high thermal hardness, wear resistance and high temperature resistance. When the hardness is above 60 m / min, there is still no obvious decrease in hardness. However, as automobile and motorcycle manufacturing, heavy industry machinery and precision instruments a...
