Medthin™ 30 - Instruments
CrN coating for surgical & dental instruments
Medthin™ 30 CrN, has silver-grey color, shows high fracture toughness, wear resistance and adhesion, making it an ideal coating for high impact and load carrying applications. The high resistance to alkaline and acidic cleaning and sterilization cycles, in combination with its other properties makes it a superior alternative to chrome plating on surgical and dental instruments. Due to its low Youngs modulus , the CrN is one of the most ductile PVD coating which can be deposited very thin (less than 1µm) as well as with coating thicknesses that can reach 10µm.
