Abstract

The invention relates to the technical field of production of hard alloy numerical control coating blades, and particularly discloses a cleaning method used before coating of a hard alloy numerical control blade. The cleaning method comprises the steps that first cleaning liquid, second cleaning liquid, third cleaning liquid, fourth cleaning liquid and fifth cleaning liquid suitable for a WC-Co type hard alloy numerical control blade base body are prepared, and the surface of a coating base body is cleaned through an improved ultrasonic cleaning process; the first cleaning liquid is powerful alkaline metal cleaning liquid; the third cleaning liquid is weak alkaline metal cleaning liquid; the fifth cleaning liquid is cleaning liquid containing an antioxidant; and the second cleaning liquid and the fourth cleaning liquid are pure water. The first cleaning liquid, the second cleaning liquid, the third cleaning liquid, the fourth cleaning liquid and the fifth cleaning liquid and the improved ultrasonic cleaning process are adopted, the cleanliness of the surface of the coating base body can be guaranteed, the production efficiency can be improved, meanwhile, it can be guaranteed that the surface of the hard alloy numerical control blade base body is not oxidized by moisture in multiple working days after cleaning, and therefore the bonding strength of the coating and the hard alloy numerical control blade base body is improved, and the service life of the hard alloy numerical control coating blade is prolonged.

Description

technical field [0001] The invention belongs to the technical field of production of hard alloy numerically controlled coating blades, and in particular relates to a cleaning method for hard alloy numerically controlled blades before coating. Background technique [0002] In the machinery manufacturing industry, cutting is one of the most widely used processing technologies. Cemented carbide has the advantages of high strength, high hardness, high elastic modulus, high red hardness, wear resistance and corrosion resistance. One of the commonly used tool materials. The main components of cemented carbide are refractory metals WC and Co. There are many factors that affect the life and performance of cemented carbide CNC tools, including the influence of geometric design, matrix composition and surface treatment process, as well as the influence of coating. In terms of compositional influence, it mainly focuses on Co content, carbon content in WC, trace elements, grain size, ...
