the experiment results including optical waveguide, film thickness control, heat treatment and thermal oxidization are reported.
报告了相应的成膜技术、膜厚控制技术、热处理技术和热氧化现象。
al also. after thermal oxidization technique, the anodic polarization curves possess wider passivity range, and self-corrosion currents are below 1/2 less than natural samples.
热氧化处理后试样的阳极极化曲线有较宽的钝化区,自腐蚀电流减小到自然态的1 2以下;
the pores generated during spraying and the cracks generated during the course of thermal oxidization because of thermal stress are the direct reasons why coatings fail.
