Orthogonal Analysis on Hardness of Nickel/Graphite Sealing Coating

Abstract:

Ni/Graphite seal coating was fabricated by flame spraying technology and the effect of oxygen pressure, the powder feeding rate and spraying distance on the coating hardness was investigated base on the orthogonal regression experimental design method. Analysis of orthogonal calculation results suggest that powder feeding rate is the key spraying influential factor valuing 140.884 which affects coating hardness; both oxygen pressure and spraying distance can be considered as secondary factors; the analysis of cross-sectional microstructure shows that the coating hardness value increases with the increase of graphite content; during coating deposition process, the content of graphite in the coating will change when adjusting the flame spraying parameters, which furthermore leads to that the coating hardness changes with variation of flame spraying parameters
