Thermal Spray Powder HVOF Coating properties： 

Thermal Spray Coating service 

Cr3C2-NiCr coating properties are influenced significantly by the spray process and spray parameters. 

The abrasive wear rate for the chromium carbide coatings is controlled by several factors such as:

the morphology of the starting powder,the size and distribution of the chrome carbide particles,the hardness of the chromium carbide particles relative to the abrasive particles

the properties of the matrix and its volume fraction, and,the coating process, which determines the coating characteristics such as:

Phase composition，Density，Hardness，Bond strength and，The residual stresses

Typical Properties of the Chrome Carbide Coating

Apparent metallographic porosity

<1.0%

Cr3C2-25NiCr, 2-25um Chromium Carbide Powder is generally best using HVOF spray. This powder offers  a dense coating that has excellent  corrosion resistance, and maximum operating temperature is 870 °C . It mainly used for hydraulic rod repair,pump rod repair,valve parts repair, , and steel rollers repair etc. The manufacturing process is Agglomerated and Sintered which can bring coating a better deposit efficiency and micro-hardness.
