Metal alloy powders are commonly used in thermal spray processes to coat surfaces with a protective or functional layer. These powders are typically made by combining different metal elements in specific compositions to achieve desired properties such as corrosion resistance, wear resistance, or thermal conductivity.

There are approximately 4,000 to 5,000 bearings manufacturing enterprises in China, and 1,750 have reached a certain scale (with sales of more than 5 million yuan). Due to the relatively high requirements for automotive bearings, from now on, there are only 30 bearing companies that can support the automotive industry in the country.
Liu Enshi, chairman of the bearing association, said: "At present, the automotive bearing industry has formed a number of leading suppliers represented by tile shafts, Luo axis, Ha-axis, universal money tide, Yoshitsuki shaft, and Hailin bearing factory. The overall development is relatively fast. However, compared with the world's most powerful bearing countries, China's bearing industry still has a large gap, and its main performance is the low proportion of high-precision, high-tech and high value-added products. It is understood that the local brand bearings in commercial vehicle bearings in China The market share is high, and one-third of them are high-precision products.
Chen Guoxi said: "The local bearing companies such as tile shaft, Luo axis, Ha-axis and other high-end products account for a higher proportion of stable and reliable product quality, and general corporate products are mainly used in the low-end car market." Wang Lushun said that in In terms of truck bearing support, domestic trucks mainly use local products. In the passenger car bearing assembly, most of the small-displacement and low-grade cars use local products, while high-end cars mainly use foreign brands.
Some commonly used metal alloy powders for thermal spray include:
1. Nickel-based alloys: These alloys are known for their excellent corrosion resistance and high-temperature strength. They are often used in applications where resistance to oxidation and wear is required, such as in gas turbine components.
2. Cobalt-based alloys: Cobalt alloys are known for their high hardness and wear resistance. They are commonly used in applications where resistance to abrasive wear and high temperatures is required, such as in the aerospace and power generation industries.
3. Stainless steel alloys: Stainless steel alloys are used for their corrosion resistance and high-temperature strength. They are often used in applications where protection against corrosion and oxidation is required, such as in chemical processing equipment.
4. Titanium-based alloys: Titanium alloys are lightweight and have excellent corrosion resistance. They are commonly used in applications where a combination of high strength, low density, and corrosion resistance is required, such as in the aerospace industry.
These metal alloy powders can be applied using various thermal spray techniques, such as flame spraying, arc spraying, plasma spraying, or high-velocity oxygen fuel (HVOF) spraying. The specific choice of alloy powder and thermal spray process depends on the desired coating properties and the application requirements.
