  • 常見元素對金屬材料性能影響的匯總

    1. 碳(1)含碳量的增加,使得碳素鋼的強度和硬度增加,而塑性、韌性和焊接性能下降。 (2)一般情況下,當含碳量大于0.25%時,碳鋼可焊性開始變差,故壓力管道中一般采用含碳量小于0.25%的碳鋼。含碳量的增加,其球化和石墨化的傾向增加。 (3)作為高溫下耐熱用的高合金鋼,含碳量應大于或等于0.04%,但此時奧氏體不銹鋼的抗晶間腐蝕性能下降。 2.硅(1)硅固溶于鐵素

  • PVD基礎知識問答

    1Target (靶材)是什幺? 答:在PVD中,靶材是用來提供鍍膜(film)的金屬材料.2PVD 制程原理為何? 答:在Target與wafer間加之高電位差,此時制程氣體Ar在高位差下解離成Ar+,又因Ar+帶正電被電場吸引而撞向Target,使target產生金屬晶粒因重力作用而掉落至wafer形成film.此種工藝是 PVD.
