The strengthening hard phases TiN/C1-xNxTi were generated by in-situ solid-gas reaction in Ni-based composite coatings prepared using a plasma spray welding process to reinforce the wear resistance of the coatings. The microstructures and properties of the coatings were investigated. The results showed that the coatings mainly consisted of phases such as TiN, C1-xNxTi, TiC, etc. A small amount ...

Abstract Corrosion performance of NiCr and NiCrBSi coatings produced by APS, HVOF, HVAF was studied electrochemical measurements immersion tests in 0.5 3.5 wt.% NaCl solutions. In the measurements, performed better than coatings. The effect coating process on corrosion resistance material significantly lower that selected materials, or NiCrBSi. All showed a tendency to passivate but suffered fr...

The superalloys are generally used for high-temperature applications, and since they operate in an aggressive environment, it is required to protect them with appropriate coating enhance the life of superalloy material. In present study, Ti-31 coated cermets Al2O3+NiCrBSi by high-velocity oxy fuel (HVOF) spray technique, hot corrosion tests were performed on both uncoated samples, presence Na2S...

Original scientific paper In this paper, influence of flame spraying and fusing on microstructure of substrates made from heat treated carbon steel C45, a heat treated low alloyed 42CrMo4 steel and stainless austenitic steel X6CrNiMo18-10-2, has been investigated. Flame spraying and fusing is a deposition technique commonly applied to nickel-base self-fluxing alloys (NiCrBSi alloys). Because of...
