But aluminum alloy with low surface hardness, wear resistance and poor drawback greatly limits the expansion of its scope of application. Therefore, on the aluminum surface enhancement, has been the focus of topics of domestic and foreign researchers.

Aluminum alloy also has low surface hardness and wear resistance such as faults, to a large extent, limit the expansion of its scope of application. Therefore, on aluminum alloy surface strengthening, is the domestic and foreign researchers focus topics of common interest.

But the aluminum alloy also has the skin hardness lowly, the wear resistant inferior shortcoming, has to a great extent limited its application scope expansion.Therefore, carries on the strengthening to the aluminum alloy surface, is always the focal point topic which the domestic and foreign resear

But there are also aluminum alloy surface hardness, abrasion resistance, as well as poor disadvantages to a large extent limits its expanding range of applications. Therefore, the aluminum alloy surface hardening, at home and abroad has been a common focus of attention of the researchers.

Aluminum alloy also has low surface hardness and wear resistance such as faults, to a large extent, limit the expansion of its scope of application. Therefore, on aluminum alloy surface strengthening, is the domestic and foreign researchers focus topics of common interest.
