PVD (Physical Vapor Deposition) coatings are versatile and widely used across various industries due to their ability to enhance the durability, performance, and functionality of materials. These coatings are applied to improve hardness, wear resistance, corrosion resistance, electrical conductivity, and optical performance, among other properties. They are a greener alternative to traditional plating methods like chrome plating, avoiding toxic byproducts. PVD coatings are used in industries such as aerospace, automotive, medical, optics, electronics, and firearms, extending the lifespan of products like surgical tools, car parts, cutting tools, and more. Their adaptability to both organic and inorganic materials makes them suitable for diverse applications, from decorative finishes to high-performance industrial uses.
