Product Description

Chrome Plated Screw

Chrome plating (less commonly chromium plating) is a technique of electroplating a thin layer of chromium onto a metal object. The product of chrome plating is called chrome. 
The chromed layer can be decorative, provide corrosion resistance, ease cleaning procedures, or increase surface hardness. Sometimes, a less expensive imitator of chrome may be used for aesthetic purposes.

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.
