Example Embodiment

[0017] Example 1:

[0018] Take stainless steel as the substrate, first carry out ultrasonic cleaning, and then use the radio frequency sputtering method in physical vapor deposition technology to remove WS 2 The solid lubricating material is deposited on the metal surface with a thickness of 0.5 μm. The obtained self-lubricating stainless steel material has a friction coefficient of 0.0355 on the surface, and has excellent wear-reducing and wear-resistant 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.

Example Embodiment

[0019] Example 2:

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

Example Embodiment

[0021] Example 3:

[0022] Using copper as the substrate, ultrasonic cleaning is performed first, and then MEVVA source ion implantation technology (metal vapor vacuum arc ion source technology) is used to bond DLC to the surface of the metal substrate to form a high-hardness lubricating film base layer 2 with a thickness of 0.005μm . Then on the DLC coating, use the radio frequency sputtering method in the physical vapor deposition technology to cover the WS 2 Coating 1 has a thickness of 0.8 μm. The obtained self-lubricating die steel has TiN high hardness and good anti-corrosion effect, and WS 2 The comprehensive function of lubrication and low friction coefficient. 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...
