Product Description
PVD Coating Screw
PVD (Physical vapor deposition) is characterized by a process in which the material goes from a condensed phase to a vapor phase and then back to a thin film condensed phase. We are using this technology on our Titanium nitride coated screws.

HVOF (High Velocity Oxygen Fuel) coating process is a kind of thermal spraying technique that melted (or heated) materials are sprayed into the surface. By HVOF technology, alloy powder spraying is under high pressure and high velocity. The adhesive force is over 10000PSI, and the powder density can be achieved up to 99.8%, which offers outstanding performance in wear & corrosion resistance.
Chrome Plating (less commonly chromium plating) is a technique of electroplating a thin layer of chromium onto a metal object. The chromed layer can be decorative, provide corrosion resistance, ease cleaning procedures, or increase surface hardness. Such screws are mainly to be used for the corrosive and other free flow material.
