The Effect of Simultaneous Incorporation of PTFE Nanoparticles and Carbon Nanotubes on the Tribological Behavior of Ni-P Coating

In some engineering fields, wear resistance and a low friction coefficient are required at the sametime. In this research, PTFE nanoparticles and carbon nanotubes were co-deposited within Ni-Pmatrix to obtain an Ni-P-PTFE-CNT hybrid coating for wear resistance and a low friction coefficient.The tribological properties of the deposits were evaluated by pin on disc tribometer. T...

Application of mesoporous silica containing benzotriazole in the epoxy coating applied to plain carbon steel and study of its corrosion behavior

The idea of smart inhibitors is based on the principle that an inhibitor is used where needed. This will reduce the use of inhibitors and protect materials in hostile environments. On the other hand, direct addition of the inhibitor within the coating can be harmful, resulting in the loss of inhibitors ability, deterioration in the coating or both of them. An appropriate method for solving thes...

Investigation of Hardness, Morphology and Structural Analysis of NiCrBSi Composite Coating on Plain Carbon Steel

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...
