The bond strength is a critical consideration for the plasma-sprayed NiCrBSi coatings. However, conventional methods testing of coatings always cost time and money. If there simple method that could predict prepared without destroying coatings, it would be significantly beneficial industrial applications. In this work, new was proposed based on total areas interfacial pores coating by plasma sp...

High velocity oxy-fuel (HVOF) is one of the emerging technologies among the thermal spraying techniques, for producing uniform and dense coatings, having high hardness and very low porosity. A NiCrBSi alloy coating was prepared with approximately 400µm thick, on the A516 steel by means of HVOF and was analyzed with regard to its detailed microstructures, phase formation, thickness, roughness an...

This article compares the creep testing behavior of AISI 4340 high-strength steel in as-received and coated conditions. The coating material used was a NiCrBSi self-fluxing alloy. microstructural characterization carried out using optical scanning electron microscopy. tests were conducted at temperature 550 °C with loads 200, 250, 300 MPa. microstructure analysis deposited layer revealed some i...

Ni-based alloy powder (NiCrBSi) was applied to prepare coatings on Ti6Al4V by laser cladding improve the wear resistance of latter under corrosion. The scanning speed found be an essential parameter that could adjust microstructure coatings. Changes in microstructures with were highlighted, and relationships between microhardness, fracture toughness, corrosion, corrosion established. Results in...
