| Outline of Final Research Achievements |
To improve corrosion and wear resistance of lightweight magnesium alloys, we proposed the joining of thin sheets of dissimilar materials by shot peening, and investigated the effects of shot peening processing conditions on the joining properties of dissimilar materials. Pure aluminum sheets and thermoplastic resin sheets were used to improve corrosion resistance, and ceramic particles were used to improve wear resistance. Corrosion resistance was evaluated by an immersion test using supersaturated sodium hydroxide, and the results showed that excellent corrosion resistance was exhibited. Wear resistance was evaluated by abrasion test by polishing, and it was found that it showed excellent wear resistance. The method proposed in the present study was found to be effective as a method to improve surface properties.

| Academic Significance and Societal Importance of the Research Achievements |
国内外において省エネルギ社会の確立が求められており、例えば、自動車や航空機などの搬送機器における軽量化は進められている。軽量化の上で、機器を構成する車体や機械部品の中における金属材料は、鉄鋼材料から軽量であるアルミニウム合金やマグネシウム合金に変更されている。しかし、これら軽金属材料の耐摩耗性や耐腐食性の表面特性は鉄鋼材料のそれに比べてかなり低く、実用化への大きな課題となっている。そこで、本研究ではショットピーニング技術を応用した新しい異種材接合技術を用いて、マグネシウム合金の表面特性の改善を試みた。その結果、本研究で得られた知見はマグネシウム合金の利用範囲を拡げる改善方法として期待される。
