Cr3C2 25NiCr Powder

PRODUCT

Introduction

Cr3C2 25NiCr powder is similar to Cr3C2 20NiCr,they both protect against abrasion, various forms of erosion and tribo-corrosion at elevated temperatures. They are well-known as an alternative to hard chromium plating with better corrosion resistance in sodium chloride, acidic and alkaline environments. HVOF coatings of these materials have good bond strength, they are dense and more homogeneous than coatings applied using atmospheric plasma spray or combustion powder flame sprayed coatings.

Plasma Spraying

Plasma spray is a thermal spray coating process used to produce a high quality coating by a combination of high temperature, high energy heat source, a relatively inert spraying medium, usually argon, and high particle velocities.

HVOF makes use of propane gas, propylene and other hydrocarbon gas or the hydrogen and high pressure oxygen burning in the combustion chamber or in special nozzle and then produces high temperature and high speed combustion flame flow.It sends powder axial into the fire,making spraying particles heat to melt or semi-molten state, and speeds up to 300-500m/s or even higher speed to obtain high quality compact coatings with good bonding strength.
