Title:
TOOL COATING PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/237957
Kind Code:
A1
Abstract:
A tool coating processing method, comprising a molten pool forming step: converging a binding phase (1) to a plasma arc heat source by means of a coaxial powder feeding passage, the bonding phase (1) being deposited on a tool base material after melting, so as to form a molten pool; and a reinforcing phase (2) adding step: sending a reinforcing phase (2) by means of a side powder feeding channel into the molten pool after a plasma beam is removed, cladding the bonding phase (1) and the reinforcing phase (2) under the condition of ultrasonic vibration, and forming a coating on the surface of a tool. The processing method solves the feeding problem, burning problem and the problem of uneven distribution in a coating of hard phase particles in a processing process of a tool coating, improves the hardness, corrosion resistance and wear resistance of the tool coating, and finally improves the service life of the tool.
