为了提高农机具深松部件的耐磨性，采用等离子堆焊技术在深松铲尖表面制备碳化铬晶粒-碳铬铁涂层，用X射线衍射仪、金相显微镜和洛氏硬度仪分析与测量了焊层的组织和性能。所制备的堆焊层组织致密，与基体铸铁材料相比，堆焊层材料的平均硬度提高了5～10倍。田间试验表明，经过该工艺处理后的深松铲尖的耐磨粒磨损性能显著提高。

In order to enhance the abrasive resistance of the agricultural tools and machinery to subsoiling component, the technique of plasma arc overlaying was used to obtain chromic carbide crystal grain -carbon ferrochrome coating on subsoi-ler surface , with X-ray diffraction instrument , the metalloscope and the Rockwell hardness tester analyzed and surveyed the layer organization and performance .The test result indicated that the welding layer prepared is uniform and dense in microstructure ,including the amorphous body ;Compared with the substrate cast iron material , overlaying compound ma-terials average degree of hardness enhanced 5~10 times .The field trial indicated that the performance of the subsoiler with abrasive wear-resisting remarkably enhanced after this processing .
