摘要

Changes in the tensile and tensile yield strengths after fusing Teflon on magnesium alloy AZ31B-H24, and aluminum alloys 2024-T3, 5052-H32, and 6061-T6 have been studied. The new technique, a flame technique, for fusing Teflon caused less alteration of the mechanical properties than the frequently used 750F oven method; aluminum alloy 2024-T3 was affected less than the other alloys. The flame or concentrated source of heat is superior to the oven method of heating because the high temperatures used are such that a rapid fusion of the coating can be accomplished without heating the bulk metal to the fusion or decomposition temperature of the coating. The new technique appears applicable to other coatings and substrates, although the thermal conductivities and heat capacities of the substrate and coating must be considered when optimum flame-fusion conditions are sought.
