Problems solved by technology

[0007] But the WS of MSC in the United States 2 The solid lubricating film still has some disadvantages that limit its wider use
Due to the combination of the film structure and the substrate, the bonding force between the lubricating layer and the substrate is low, and the lubricating surface of the moving parts is easy to wear when the load is large, and the corrosion resistance is not strong, and the equipment investment is large and the price is too high, which limits the its development

Embodiment 1

[0018] Using stainless steel as the base material, ultrasonic cleaning is performed first, and then radio frequency sputtering in physical vapor deposition technology is used to deposit WS 2 The solid lubricating material is deposited on the metal surface with a thickness of 0.5 μm. The friction coefficient of the surface of the obtained self-lubricating stainless steel material is 0.0355, and has excellent wear-reducing and wear-resisting properties. The wear rate before and after coating decreased from 2.486×10-5g / m to 0.399×10-5g / m., and the friction coefficient decreased from 0.29 to 0.0355.

Embodiment 2

[0020] Using die steel as the base material 3, ultrasonic cleaning is first performed, and then the MEVVA source ion implantation technology (metal vapor vacuum arc ion source technology) is used to bond TiN to the surface of the metal substrate to form a base layer 2 of lubricating film with high hardness, with a thickness of 0.005 μm. Then on the TiN coating, WS is covered by RF sputtering in physical vapor deposition technology. 2 Coating 1 with a thickness of 0.8 μm. The obtained self-lubricating die steel has high TiN hardness and good anti-corrosion effect, and WS 2 Comprehensive functions of lubrication, high temperature resistance and low coefficient of friction. And because the processing thickness of the double-layer lubricating cladding layer is micron level, it can meet the matching tolerance between the mold and the processed parts, reduce the processing cost, and is suitable for the processing and production of various wear-resistant molds.

Embodiment 3

[0022] Using copper as the base material, first perform ultrasonic cleaning, and then use MEVVA source ion implantation technology (metal vapor vacuum arc ion source technology) to bond DLC to the surface of the metal substrate to form a high-hardness lubricating film base layer 2 with a thickness of 0.005 μm . Then on the DLC coating, WS is covered by radio frequency sputtering in physical vapor deposition technology. 2 Coating 1 with a thickness of 0.8 μm. The obtained self-lubricating die steel has high TiN hardness and good anti-corrosion effect, and WS 2 Comprehensive function of lubricating low coefficient of friction. It is suitable for the processing and production of various wear-resistant moving parts.

Abstract

The invention discloses a self-lubricating metallic material. The self-lubricating metallic material is prepared by the following steps of: coating a substrate layer on the surface of a metallic material by adopting an MEVVA source ion implantation technique; and then coating a WS2 lubricating layer on the surface of the processed metallic material by using an RF radio frequency sputtering process in PVD. The self-lubricating metallic material obtained by the invention is load resistant, corrosion resistant, abrasion resistant and high temperature resistant, and is suitable for manufacturing moving parts in various common and extreme environments.

Description

technical field [0001] The invention belongs to the field of metal materials, in particular to a self-lubricating metal material. Background technique [0002] At present, liquid lubricants are commonly used in the industry, which are coated on the metal surfaces of instruments for lubrication. With the development of science and technology and the increase of machine types, it is often difficult for grease lubricants to meet the requirements, mainly because grease lubricants are difficult to play a role for a long time under high temperature conditions, or even lose their effect. [0003] In the past 30 years, the international community has attached great importance to the research and production of solid lubricating materials. During World War II, the United States began to research and develop solid lubricating projects, such as the development of MoS2 solid lubricating coatings. In the 1950s, the United States formulated the American military standard for molybdenum di...
