research and progress on metal materials surface strengthening in china by high intensity pulsed ion beams 强流脉冲离子束金属材料表面强化技术在中国的研究进展
vibration strengthening and polishing technique is adopted for carrying out surface strengthening and polishing processing upon complicated work piece with unusual typed curved surface 摘要振动强化、抛光技术用于对复杂异型曲面工件进行表面强化、抛光处理。
strengthening mechanism of ion nitriding is different from surface quenching and cementation, which makes surface strengthen by quenching to get martensite . ionic nitriding is the way to make materials strengthe n, which result from the steady compound formed on the surface of the metal . there is no need for quenching after treatment 离子渗氮的强化机理不同于表面淬火,渗碳等表面热处理方法,这些方法必须进行淬火得到马氏体使表面强化,而离子渗氮是在金属表面形成稳定化合物而使材料强化,处理后不须淬火。
