CIM developed TungHard™ PTA Tungsten Carbide Overlay for Highly Abrasive Conditions


CIM developed TungHard™ for extremely abrasive applications. It is made from 70% spherical tungsten carbide dispersed in NiCrBSi matrix by Plasma Transferred Arc (PTA) welding process. The tungsten carbide hardness is 2700- 2900 HV, and the bulk hardness of NiCrBSi matrix is 60-70 HRC. Both the prime carbide and the matrix are very hard to withstand low stress abrasion in tailing line, pump suction & discharge spools and wear spools.


The TungHard™ could increase 5-6 times life comparing to Chrome Carbide overlay (CCO).
