Problems solved by technology

[0002] A casing part has the characteristics of thin wall, ring shape, complexity and high design precision. The material of this part is a new type of material titanium alloy TC25, and the inner cavity should be sprayed with GH3030 coating by flame melting method. The GH3030 coating fell off as a whole, and the large-area or local block-off rate reached more than 80%, and the qualified rate of one spraying was only 15.65%, which led to a sharp decline in the quality of the casing, seriously affecting product quality and production progress, and economic losses. great
Since there are no references for GH3030 coating parameters for titanium alloy (TC25) casings in the prior art, it is necessary to develop new processing methods whether it is coating spraying or coating lathe processing

Embodiment Construction

[0013] The technical scheme of the present invention will be further described below in conjunction with the accompanying drawings, but the required protection scope is not limited to the description;

[0014] Such as figure 1 As shown, in order to solve the problem of overall peeling, large area or local block falling of the coating, methods such as controlling the coating thickness\turning route are adopted respectively.

[0015] Coating processing method of the present invention is as follows:

[0016] 1) Case cleaning:

[0017] After washing the casing, dry it to keep the surface of the casing dry, clean and free of sundries and contamination. Specifically, use a brush dipped in acetone or other solvents to carefully scrub the casing to completely remove oil and other dirt on the surface of the parts.

[0018] 2) Case spray coating

[0019] The flame melting method is used to spray the GH3030 coating on the spraying part of the casing, and the coating thickness is cont...

Abstract

The invention discloses a method for machining a machine case coating. The method comprises the steps of carrying out coating spraying and carrying out coating turning machining, for coating spraying,a GH3030 coating is sprayed to a to-be-sprayed part of a machine case by adopting a flame burning-melting method, and the thickness of the sprayed coating is less than 0.7 mm; and for the mode of coating turning machining, turning machining is carried out starting from the axial bisection surface of the machine case twice, and turning machining is carried out by 1 / 2 circumferential surface for each time. According to the method for machining the machine case coating, high-precision machining of the machine case can be realized, and then the problems of integral shedding, large-area or local falling and the like of the coating can be prevented from occurring.

Description

technical field [0001] The invention belongs to the technical field of surface treatment, in particular to a processing method for spraying a GH3030 coating on a casing inner cavity made of titanium alloy (TC25) using a flame melting method. Background technique [0002] A casing part has the characteristics of thin wall, ring shape, complexity and high design precision. The material of this part is a new type of material titanium alloy TC25, and the inner cavity should be sprayed with GH3030 coating by flame melting method. The GH3030 coating fell off as a whole, and the large-area or partial block-off rate reached more than 80%, and the qualified rate of one spraying was only 15.65%, which led to a sharp decline in the quality of the casing, seriously affecting product quality and production progress, and economic losses. great. Since there are no references for GH3030 coating parameters for titanium alloy (TC25) casings in the prior art, new processing methods need to be...
