PVD vacuum coating process and coating workpiece

Abstract

The invention discloses a PVD vacuum coating process. The PVD vacuum coating process comprises the following steps that 1, the surface of a base material is treated, specifically, the surface of the base material is wiped and washed, and degreasing and dedusting treatments are conducted; and the cleanness and dryness of the base material are ensured; 2, prime coating and drying of the base material are conducted, specifically, the surface of the base material is coated with coating oil, then drying is conducted, the drying temperature is 60-70 DEG C, and the drying time is 2 hours; 3, coatingis conducted, specifically, the base material in the step 2 is placed in a vacuum coating furnace, a vacuumizing device vacuumizes the vacuum coating furnace, and after the vacuum degree reaches the requirements, the vacuum coating furnace starts coating; 4, cleaning is conducted, specifically, the coated workpiece is put into an ultrasonic cleaning device for cleaning; and 5, drying is conducted,specifically, the cleaned workpiece is dried, and packaging is conducted.

Description

technical field [0001] The invention belongs to the technical field of PVD vacuum coating, and in particular relates to a PVD vacuum coating process and a coating workpiece. Background technique [0002] Empty coating is an important aspect in the field of vacuum applications. It is based on vacuum technology, uses physical or chemical methods, and absorbs a series of new technologies such as electron beams, molecular beams, ion beams, plasma beams, radio frequency and magnetron. Scientific research and practical production provide a new process for thin film preparation. Simply put, the method of evaporating or sputtering metals, alloys or compounds in a vacuum to solidify and deposit them on the coated object is called vacuum coating. [0003] The following deficiencies exist in the existing PVD vacuum coating process: during the workpiece coating process, the workpiece is hung on the workpiece hanger for spray coating.

Problems solved by technology

[0003] The following deficiencies exist in the existing PVD vacuum coating process: during the workpiece coating process, the workpiece is hung on the workpiece hanger for spray coating. Coating nozzle, its coating film is not uniform, so that the partial film layer of the workpiece is unqualified; the vacuum pump used for vacuuming will vibrate during operation, and the noise generated greatly affects the working environment of the factory personnel, and the vacuum pump connected Due to the long-term extrusion of the atmospheric pressure, the internal stress of the vacuum tank is difficult to eliminate, which will easily lead to bursting; at present, the knives are manually put into the cleaning pool of the ultrasonic cleaning machine. and there is a risk of injury
