...Rakesh Goyal; Khushdeep Goyal; Punam Goyal Purpose This study aims to analyze the hot corrosion behavior of Cr3C2 coatings mixed with varying amounts of NiCr on T11 boiler steel under high-temperature conditions. It evaluates the corrosion resistance of different coatings using thermogravimetric...

... the material’s erosion behavior. In this work, the experimental investigation of SS-304 with sand was done with sand as the erodent material on a tester with various parameters. Further, the materials were made more resistant to wear by a WC-10Co-4Cr coating, done by the high-velocity oxygen fuel method...

...Karanjit Singh; Khushdeep Goyal; Rakesh Goyal Purpose This paper aims to investigate hot corrosion behaviour of different Cr₃C₂–NiCr coatings on boiler tube steel. Design/methodology/approach High velocity oxy fuel technique has been used to deposit different coatings...

... as a dispersing agent (uncoated Cu particles). Polypyrrole (PPy)-coated Cu nanoparticles were also used as the filler. Strong bonding for Cu discs was not obtained by using the PPy-coated particles. For the uncoated Cu particles, a shear strength required for separating the discs bonded by annealing at 400°C...

...S. Meziani; A. Fouathia This work relates to the characterization with indentation of the hard chromium coatings, carried out by electrolytic way on a steel substrate. Steel thus covered is used for the construction of the jacks of industrial machines. We studied in this work the effect of size...
