In the medical field, the application of thermal spraying technology embodies its unique combination of precision and user-friendliness. The surface treatment of artificial joints demands extremely high biocompatibility, requiring them to be compatible with human tissue while also possessing sufficient wear resistance to withstand daily activities. Hydroxyapatite coatings created using thermal spraying technology, with a composition similar to the inorganic components of human bone, promote the growth of bone cells on the surface of artificial joints, achieving "osseointegration." This not only strengthens the implant but also reduces the impact of wear debris on the body, significantly improving patients' quality of life. From large-scale equipment in heavy industry to medical devices critical to life and health, thermal spray technology, with its unique "coating magic," solves practical problems in diverse scenarios. As the technology continues to advance, we believe it will create unexpected application value in even more fields, continuously bringing convenience and breakthroughs to our daily lives.
