Abstract

The invention discloses a surface treatment method of a saw web. According to the method, a composite film which is low in friction coefficient and good in toughness is deposited on the surface of thesaw web by the aid of a gas ion source with the high-power pulse technology and the electric arc technology. The method includes the following steps that gas ion source cleaning is performed on the saw web; the saw web is subjected to ionic nitriding by the aid of the gas ion source; and a coating adopting a composite laminated structure is deposited with the high-power pulse technology and the electric arc technology. The prepared sandwich composite film layer has the high toughness, the high micro-hardness and the low friction coefficient, the service life of the saw web can be obviously prolonged by 2-5 times, and the method has the very good application prospect in the field of saw webs.

Description

technical field [0001] The invention relates to the technical field of surface modification of ion beam materials, in particular to a deposition method and related equipment for improving the service life of saw blades. Background technique [0002] A saw blade is a general term for thin, circular knives used to cut solid materials. Saw blades can be divided into diamond saw blades for stone cutting, high-speed steel saw blades for metal material cutting; Quality alloy saw blade. Due to different uses, the material and hardness of saw blades are also different. Band saw blades and circular saw blades are usually used for sawing metal materials. The band saw blade has good versatility and can cut larger workpieces, but compared with the circular saw blade, the sawing efficiency and cutting surface quality are far inferior to the latter. Circular saw blade metal sawing is widely used in the mechanical processing industry. In order to achieve the goal of low carbon, environ...
