In modern industrial production, roller equipment such as rolling rollers, conveying rollers, and drying cylinders serve as the backbone of production lines. These components endure constant exposure to immense pressure, intense friction, high temperatures, and corrosive environments. The surface quality of these components directly determines production efficiency, product quality, and service life. 

In the field of mining machinery engineering, extreme working conditions remain the core challenge hindering stable equipment operation. Underground mining environments are confined and narrow, with high-concentration dust continuously eroding equipment surfaces.

Ferrous metal materials (currently the most mainstream application)
1.Medium and high carbon steel (carbon content 0.3%~0.8%), typical materials: 45 steel (high-quality medium-carbon structural steel), designated as S45C in JIS standards, ASTM 1045/080M46, and DIN C45, is a premium carbon structural steel with the following chemical composition: 

With the rapid development of the automotive industry and continuous advancements in manufacturing capabilities, automotive molds have become critical process equipment in automobile production. Their quality and performance directly determine the precision, lifespan, and production efficiency of automotive components. 

Laser quenching is a cutting-edge process that uses high-energy laser beams to heat material surfaces beyond their phase transition points. As the material naturally cools, austenite transforms into martensite, creating a hardened layer with exceptional hardness and wear resistance on the product's surface. 

Beneath the depths of coal mines, hydraulic support columns in fully mechanized mining systems oscillate under 10,000-ton pressures, scraper conveyor troughs grind against coal gangue, while hydraulic cylinders struggle to operate in humid and corrosive environments.

Aerospace engines, hailed as the "crown jewel" of modern industry, endure relentless challenges with their core components like high-pressure turbine blades and transmission gears. These critical parts constantly withstand extreme temperatures, pressures, and rotational speeds.

During the maintenance and repair of motors, parts often become dimensionally unsuitable due to long-term operation, wear, or improper assembly. For example, the bearing seat of the motor shaft becomes smaller due to wear, and the bearing chamber becomes larger due to looseness.

Ship corrosion remains a significant challenge in the global shipping industry. According to statistics, global direct economic losses from ship corrosion exceed $100 billion annually. The performance limitations of traditional anti-corrosion coatings in the extreme marine environment have made the search for more advanced protection technologies a pressing need.
