melting surface layer的意思|示意

And laser surface engineering has been widely applied in industrial processes due to inducing melting of a thin layer on metal surface when operated at higher intensity.

激光表面工程是在高能激光束流的作用下于金属表面形成一熔化的薄层而在工业上广为应用。

Recent developments and applications of laser surface modification, i. e. laser surface melting, laser surface alloying, laser cladding and laser multi-layer cladding were reviewed in detail.

综述了激光表面改性(激光表面重熔、激光表面合金化、激光表面熔敷、激光多层熔敷)的研究与应用。

The results show that the laser surface melting treatment improves greatly the homogenization, compaction and the corrosion resistance of rare earth permeating layer under the condition of test.

结果表明，在一定条件下，激光熔凝处理可进一步提高纯铁渗稀土层组织的致密性与均匀性，显著提高稀土渗层的耐蚀性。

But it has low melting point and sintering point, when it is used to extinguish a fire, it can rapidly decompose to form a layer of film, which can cover the surface of comburent and make the fire.

但低聚磷酸铵具有较低的熔点和烧结点，用来灭火时能迅速分解形成膜层覆盖于燃烧物表面使火焰熄灭。
