Technology Overview

Question 1

Physical Vapor Deposition (PVD) Coating

Accepted Answer

Physical Vapor Deposition (PVD) Coating PVD technology generates an arc discharge with high current and low voltage in a high vacuum environment, causing it to impact the metal target, which triggers cathodic arc light and plasma flow. A negative bias power supply is applied to the substrate to direct the positively charged ions from the dissociation to the substrate, resulting in thin-film deposition. Advantages: Competitive cost (easily automated in-line arrangement) Thickness precision (±0.1um) Better coverage coating capability PVD Chamber-type Equipment

Question 2

Cold Gas Spray (CGS)

Accepted Answer

Cold Gas Spray solutions offer significant cost-effectiveness for thick coatings (>50um) and possess excellent bonding strength and non-contaminating characteristics. Cold Gas Spray is a mature physical coating technology, where high-pressure gas is preheated and passed through a nozzle to generate a supersonic gas jet. The powder is heated and accelerated, then impacts the substrate in a solid state, forming a deposit. It can be used both as a coating process or as an additive manufacturing technique. Substrate: Metal / Ceramic / Plastic, etc. Additive Materials: Copper / Tin / Silver / Titanium, etc. Cold Gas Spray Equipment
