Problems solved by technology

The preparation process of self-lubricating coating includes electroplating, chemical plating, thermal spraying, PVD, CVD, etc. The disadvantage is that the bonding strength between the coating and the base metal is low, the coating is easy to peel off when it is impacted, and there are defects such as holes, slag inclusions, and cracks.
More advanced preparation techniques include plasma-enhanced chemical vapor deposition, plasma ion implantation, plasma-assisted physical vapor deposition, supersonic flame spraying, unbalanced magnetron sputtering, etc. question
In addition, the preparation process of this kind of coating is complicated, and the coating is uneven, which greatly affects the lubrication effect, so it is difficult to apply to large workpieces

Description

technical field [0001] The invention relates to the anti-friction and anti-corrosion technology of metal components, in particular to a wear-resistant self-lubricating anti-corrosion coating and its preparation method and application, which belong to the field of fine chemical industry. Background technique [0002] Fatigue fracture, corrosion and wear of materials are the three major causes of material failure. It is understood that in my country's industrial sector, the loss caused by equipment shutdown and scrapping due to corrosion and wear and other reasons accounts for nearly 10% of the annual GDP, and the loss is as high as 100 billion yuan. About 30% of the energy in industrialized developed countries in the world is consumed in wear and tear in different forms. Slowing down the corrosion and wear of metal materials is an important guarantee to ensure the normal and safe operation of equipment and reduce maintenance times. [0003] Common self-lubricating coatings ...
