The invention relates to a preparation method for an alloy sample surface wear-resisting protective layer. Firstly, an alloy sample is subject to micro-arc oxidation treatment, and a multi-hole micro-arc oxidation layer is obtained on the alloy sample surface; and secondly, a sealant is applied to the alloy sample surface. According to the preparation method, through the technologies of micro-arcoxidation, sealant applying and the like, an even micro-arc oxidation layer and lubrication particle composite self-lubricating wear-resistant coating is prepared on the alloy sample surface, the characteristic that micropores and lubrication particles are organically bonded is effectively used, and the antiseptic, wear-resisting and lubricating properties are greatly improved. 本发明涉及种合金样件表面耐磨防护层的制备方法，先对合金样件进行微弧氧化处理，在合金样件表面获得多孔的微弧氧化层；然后在合金样件表面施加封孔剂。本发明通过微弧氧化和添加封孔剂等技术在合金样件表面制备出均匀的微弧氧化层和润滑颗粒复合的自润滑耐磨涂层，有效利用微孔和润滑颗粒有机结合的特点，实现合金材料的防腐、耐磨与润滑性能的极大提高。
