Supersonic velocity fuel Tungstne carbide jet Specs

　   To control the quality of the coating, company imported full sets of test instruments and build coating development and inspection capacity. Before each coating operation, a sample plate is tested and inspected, including porosity, homogeneity, micro hardness, etc. Only when the best specs are confirmed, the operation can start. Such operation-test-operation process guaranteed the layer quality and help operators to get the best specs.

　　Porocity： ≤1

　　Layer Micro Vickers HardnessHV 0 . 1 ( 1100 - 1300 )

　　Combination strength of coating and base metal ≥70 MPa
