Medthin™ 43 ADLC
ADLC coating for surgical instruments
Medthin™ 43 ADLC is a dual layer coating with a SiC base layer followed by top DLC (carbon) layer. The two layers confer to Medthin™ 43 ADLC extreme smoothness, high density and hardness. Medthin™ 43 ADLC has been designed to minimize the friction coefficient and ADLC can work against ADLC in dry mode. This fine coating requires a high level care in surface preparation prior to coating and it justifies to be used only if the top performance is required, such as nearly no wear and extremely low friction coefficient. Its application on surgical instruments must be discussed with our engineers.
