Micro arc discharge surface treatment on BO1 steel

The abrasive wear resistance of BO1 steel is significantly improved when treated with the micro arc process. After treatment both the material bulk properties and dimensions of the treated samples (with the exception of the surface roughness) were unchanged. Parameters such as electrode stand-off distances, oil film thickness, and electrode shape, greatly influences the final characteristics of the surface. Meticulously polishing the substrate surface before treatment lead to a uniform distribution of hard carbides on the treated surfaces. Samples treated for short duration display better wear resistance due to their smoother surfaces. However, those treated for longer durations have very hard carbides that extend far deeper into the surface. This is a desirable characteristic for tools subject to combined abrasive and erosive wear.

BO1钢上的微电弧放电表面处理

采用微弧工艺处理后,BO1钢的耐磨性得到了显着改善。处理后,材料的整体性能和经处理样品的尺寸(表面粗糙度除外)均保持不变。电极间隔距离,油膜厚度和电极形状等参数极大地影响了表面的最终特性。在处理之前认真抛光基板表面会导致硬质碳化物在处理过的表面上均匀分布。经过短时间处理的样品由于表面光滑,因此具有更好的耐磨性。但是,那些经过较长时间处理的碳化物具有非常硬的碳化物,它们延伸到表面的深度更深。对于遭受磨蚀和侵蚀磨损的工具来说,这是理想的特性。
