摘要： PURPOSE:To form a sprayed ceramic film having superior stripping resistance on a base material of Al or an Al alloy by forming an under layer on the base material heated to a proper temp. by spraying and by spraying a ceramic material on the under layer. CONSTITUTION:An under layer is formed on a base material of Al or an Al alloy heated to 130-250 deg.C by spraying. The under layer is preferably made of an Ni-Cr alloy contg. 15-25wt% Cr or an Ni-Al alloy contg. 4-22% Al. A ceramic material is then sprayed on the under layer. The optimum ceramic material is a stabilized zirconia-base material having high stability at thigh temp., low heat conductivity and a coefft. of thermal expansion which is relatively close to that of the metal of the base material and that of the metal of the under layer, and the ceramic material is sprayed to about 0.2-1.0mm thickness.
摘要翻译：目的：通过在加热到适当温度的基材上形成底层，形成在Al或Al合金的基材上具有优异的耐剥离性的喷涂陶瓷膜。通过喷涂和在底层上喷涂陶瓷材料。构成：通过喷涂在Al或Al合金的基材上形成底层，加热到130-250℃。底层优选由Ni-Cr合金制成。 15-25wt％Cr或Ni-Al合金 4-22％Al 然后将陶瓷材料喷在底层上。最佳陶瓷材料是稳定的氧化锆基材料，在大腿温度下具有高稳定性，低导热性和系数。的热膨胀相对于基材的金属和下层的金属的热膨胀，并且将陶瓷材料喷涂到约0.2-1.0mm的厚度。
