一般地，铸造组织为树枝晶组织，组织成分不均匀；
In general, dendrites occur in the microstructure of castings and the distribution of chemical elements is not homogeneous.
优点：可以破坏钢锭的铸造组织，细化钢材的晶粒，并消除显微组织的缺陷，从而使钢材组织密实，力学性能得到改善。
Advantages: it can destroy the ingot casting, steel grain refinement, and eliminating the defect in microstructure, thus making steel tissue close-grained, with improved mechanical properties.
激光上釉是通过细化铸造组织、减少偏析及形成高度过饱和固溶体等亚稳定相乃至非晶态而提高了材料的耐磨性、抗氧化性和抗腐蚀性能。
Laser glazing gives potential to enhance wear-resistance by refining grain structure, reducing segregation, producing supersaturation solid solution body and metastable or amorphous phases.
