How does precision machining realize the surface treatment of parts?

  • 2022-02-17 14:41:25

With the development of modern science and technology, the performance of modern industry on the surface of various equipment parts is also getting higher and higher, especially the parts after precision machining, which work under the conditions of high temperature, corrosion, high speed, high pressure, etc. Destruction often starts at the surface. For example, high-temperature oxidation, wear, etc., local damage to the surface often leads to the failure of the entire part, which eventually leads to the shutdown of the equipment.


How to avoid similar phenomena in these parts, improving the surface properties of materials to increase service life, save resources, and improve production efficiency has become an important task, and now the biggest advantage of surface treatment of metal parts is that it can be manufactured in a variety of ways and methods The surface layer with better performance than its own material can make the precision machined parts have higher wear resistance and high temperature resistance.


At present, modern enterprises use physical methods, chemical methods, electrochemical methods and high vacuum methods to treat the surface of metal parts, and carry out corresponding coating and treatment on the surface of parts to form a protective layer with special functions.
Classification of surface treatment:
1) Electrochemical method: electroplating, anodizing
2) Chemical method: chemical conversion coating treatment, chemical plating
3) Thermal processing method: thermal spraying, chemical heat treatment, hot dip plating

4) Vacuum method: ion implantation, chemical vapor deposition, physical vapor deposition

The average benefit of processing precision-machined parts by the above methods is as high as 5-20 times. Metal surface treatment can directly prevent the failure of many precious non-standard parts. Local surface strengthening repair is implemented, and the purpose of pre-protection measures is to prolong or restore the use value of some parts.
