The application prospects of diamond in the aerospace field

Diamond, due to its unique physical properties, such as high hardness, high thermal conductivity and excellent chemical stability, is widely used in many fields. In recent years, with the continuous advancement of science and technology, the application prospects of diamond in the aerospace field have become increasingly apparent.

Physical and chemical properties of diamond

1. Ultra-high hardness

Diamond is the hardest substance in nature. Its hardness is as high as 10,000HV, which is 40 times the commonly used hardness. It can resist wear and scratches of most materials. In the aerospace industry, this hardness makes diamond an ideal material for making tools, cutting equipment and protective coatings.

2.Good thermal conductivity

Diamond has extremely high thermal conductivity and low thermal expansion coefficient, and can effectively conduct heat, so it has good application potential in high-precision instruments and equipment.

3.Excellent chemical stability

Diamond is highly resistant to corrosion and remains stable in harsh aerospace environments.

Diamond applications in aerospace
