Abstract

The invention relates to a method for planting a solid lubricating material in a laser microporous template, which belongs to the field of solid lubricating materials; the specific process is carried out according to the following steps: (1) The laser microporous template is made; Drill micropores on the surface of the cladding layer; (2) Before deposition, acid wash off the spatter on the surface of the template; (3) Plant a mixed lubricating material of molybdenum disulfide (MoS2) and polytetrafluoroethylene (PTFE) by electrophoretic deposition in micropores; (4) drying in an oven after deposition; (5) densification of the lubricating layer by microwave sintering. The lubricating layer obtained by the method of the invention stores the lubricating material through the micropores on the surface of the wear-resistant substrate, and slowly releases the lubricating material in the process of friction to play a continuous lubricating effect, thereby greatly improving the lubricating life.

Description

technical field [0001] The invention relates to the technical field of solid lubrication, and more specifically relates to a method for planting MoS in laser microporous templates. 2 Mix solid lubricating material with PTFE. Background technique [0002] There are three types of lubricating materials: liquid lubricants (lubricating oil), semi-solid lubricants (grease) and solid lubricants. Compared with lubricating oil and grease, solid lubricants have great advantages. The temperature range of lubricating oil and grease is very narrow. Beyond this temperature range, lubricating oil and grease will lose their lubricating effect, while solid lubricating materials have a wide range of applications; in terms of carrying capacity, solid lubricants are far stronger For lubricating oil and grease; under extreme conditions such as high vacuum, strong radiation, and gas or fluid, lubricating oil and grease are prone to failure, and solid lubricants are also needed; the storage, tr...
