Porosity of detonation-deposited chromium carbide-base coatings

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

The variation of the open porosity of a coating as a function of detonation-deposition process conditions matches that of the quality of the coating as assessed by other parameters. The open porosity of a coating is strongly affected by its surface roughness, and consequently estimates of πop may be high. The size of a specimen for open porosity testing should not be greater than 1.2 times the barrel bore. Under optimum conditions the visible porosity of coatings does not exceed 1%.
