It has been investigated for Belag (oxide protective film) formation interface, and the utilization of the results has been considered. Major following results were obtained.1. It was found that Belag adhere without the reaction layer on the worn surface selectively by thermoelectromotive force generated during cutting, and adhere directly to the Ti compounds. This is why it does not form on the carbide K grade. Then, FeO is concentrated at the interface when cutting time becomes longer, leading to wear by diffusion reaction. 2. When machined the Ca deoxidized steel, including MnS, CaS layer occurs in Belag bond interface. As the result, tool life prolongation will be possible by preventing the concentration of FeO. 3. Differences were observed in the adhesion by the mineral water mist machining and the crystal orientation of the coating film. Potential as a method for reducing adhesion of workpiece has been found, including non-ferrous materials that results in severe adhesion.

已经研究了Belag（氧化物保护膜）形成界面，并考虑了结果的利用。获得了以下主要结果。1。发现Belag粘附在切割过程中产生的热电动力选择性地上没有反应层，并直接粘附在Ti化合物上。这就是为什么它不在碳化物K级上形成的原因。然后，当切割时间更长时，将FEO集中在界面上，从而导致扩散反应的磨损。 2。当加工CA脱氧钢（包括MNS）时，CAS层发生在Belag键界面中。结果，通过防止FEO的浓度来实现刀具寿命的延长。 3。通过矿物水雾加工和涂料膜的晶体取向观察到差异。已经发现了一种减少工件粘附的方法，包括导致严重粘附的非有产材料。
