据美刊《材料工程》1987年第1期报道,美国国家航空和航天管理局发明了一种新的涂覆工艺,亦取得了专利权,这种工艺避免了用传统快速凝固金属涂覆大表面工件的工艺所存在的许多问题。快速凝固金属具有非晶型或微晶型组织,作为涂层有很多的优点,例如能提供极好的耐磨性能和耐蚀性能。它们常常是用离子涂覆、激光“上釉”或离子移置的方法加到工件表 According to the American Journal of Materials Engineering, 1987, No. 1 report, the United States National Aeronautics and Space Administration invented a new coating process, also obtained a patent, this process avoids the use of traditional rapid solidification of metal coating large Many problems with the surface work piece process. Rapidly solidified metals have an amorphous or microcrystalline structure and have many advantages as coatings, for example, providing excellent wear resistance and corrosion resistance. They are often applied to workpieces by ion-coating, laser “glazing” or ion displacement
