This investigation compared the tensile bond strengths of a nickel-chromium-beryllium alloy etched electrolytically and etched with a commercially available chemical gel. The number of applications and the thermal conditions of the chemical etchant were varied to assess their influence on the composite-to-metal tensile bond strength. Etched metal cylinders were bonded end-to-end with a resin luting agent and were subsequently tested for tensile strength. Etch patterns, mean bond strengths, and mode of failure were recorded. Significant differences relating to the application number and the thermal conditions of the chemically etched specimens were noted.
本研究比较了经电解蚀刻和用市售化学凝胶蚀刻的镍铬铍合金的拉伸粘结强度。改变化学蚀刻剂的应用次数和热条件，以评估它们对复合材料与金属拉伸粘结强度的影响。将蚀刻后的金属圆柱体用树脂粘结剂端对端粘结，随后测试其拉伸强度。记录蚀刻图案、平均粘结强度和失效模式。观察到化学蚀刻试样在应用次数和热条件方面存在显著差异。
