Vacuum plasma spraying, VPS
About the process
In vacuum plasma spraying, an electrical arc is created in a low-pressure atmosphere. At the start of the process, the atmosphere inside the process chamber is pumped down to a pressure of below 0.1 mbar. This ensures that reactive gases (oxygen and hydrogen) do not adversely affect the subsequent coating process. As with atmospheric plasma spraying, the spray powder particles are injected into the plasma jet, accelerated and melted. Due to the VPS atmosphere the melted metal particles do not oxidize. In is way high-purity Titanium layers are built up on the surfaces of the implants.
Medicoat creates turnkey VPS systems and components for vacuum plasma spraying - individually adapted to the customer needs.
