Method for coating film and setting patterns on surface of workpiece

Abstract

A method for coating a film and setting patterns on the surface of a workpiece belongs to the field of coating and pattern setting of surfaces of workpieces. The method includes steps of (1), realizing PVD (physical vapor deposition) vacuum ion coating on the surface of the workpiece; (2), designing the patterns; (3), photographing the patterns; (4), developing a black and white negative film of the patterns; (5) spraying acid-resistant sensitizer on the surface of the workpiece after the surface of the workpiece is treated in the step (1); (6), setting the black and white negative film on the surface of the workpiece after the acid-resistant sensitizer is sprayed on the surface of the workpiece; (7), irradiating ultraviolet rays on the surface, including the portion covered by the black and white negative film, of the workpiece; (8), corroding PVD vacuum ion coatings outside patterns on the surface of the workpiece by acid solution; and (9), removing the sensitizer on the patterned surface of the workpiece by alkaline medicinal liquid and obtaining a finished product with the patterns. The method is used for coating the film and setting the patterns on the surface of the workpiece, the grade of the appearance of the produced product can be improved, the produced product is more striking and attractive, a good decorative effect is realized, and the method is low in production cost and fine in economic benefit.

Description

technical field [0001] The invention relates to the technical field of coating and patterning on the surface of a workpiece, in particular to a method for coating and patterning on the surface of a workpiece. Background technique [0002] At present, there are patterns on jewelry and other daily necessities such as mobile phone cases, watch straps, belt buckles and eyeglass frames. The purpose of setting patterns on the surface of the above products is to improve the grade of the product in appearance and make it more attractive. Eye-catching and beautiful, in order to gain the favor and recognition of consumers and achieve the purpose of expanding product sales. In the prior art, in order to set patterns on the surface of these products, it is first necessary to manually draw a picture, and the pattern can be set on the surface of the product after complex production processes. Manually drawn pictures, the quality of the picture is not high, the drawing speed is slow, it t...

Problems solved by technology

In the prior art, in order to set patterns on the surface of these products, it is necessary to manually draw a picture and go through a complex production process to set the pattern on the surface of the product

Manually drawn pictures, the quality of the picture is not high, the drawing speed is slow, it takes a long time, the labor cost is high, the decorative effect of the product is poor, and the pattern adhesion ability on the product is poor, that is, the pattern on the product is poor in stability

Enterprises producing these products have high production costs and poor economic benefits
