基体预处理对CrN涂层刀具表面粗糙度和膜基结合力的影响
|
摘要
通过M2高速钢基体抛光预处理工艺,获得表面粗糙度和膜基结合强度良好的Cr N硬质涂层。采用正交法设计了不同压力、砂料、干湿方式等喷砂工艺参数进行高速钢基体预处理工艺研究。对预处理后的基体采用多弧离子镀技术沉积Cr N硬质涂层。通过扫描电镜、XRD、粗糙度仪和划痕测试仪等仪器检测分析了Cr N涂层的形貌、涂层物相结构、涂层粗糙度和涂层结合力等组织性能。喷砂压力较大和砂料硬度较高时,其涂层粗糙度较大,膜基结合强度较小。对采用玻璃珠砂料在2bar压力下进行干喷砂预处理后的基体进行涂层处理,其涂层综合性能最好,其膜基结合力为78N,涂层表面粗糙度为0.369μm,涂层厚度约为5μm,涂层厚度均匀,涂层表面比较平整致密,基本未见明显的孔洞结构。
The Cr N hard coatings with good surface roughness and good bonding strength were obtained on the M2 high speed steel substrate pretreated by polishing.The process parameters of high speed steel substrate pretreatment were studied by orthogonal design,such as different pressure,sand,dry or wet process parameters.The Cr N hard coating was deposited on the pretreated substrate by multi-arc ion plating technique.The morphology,coating phase structure,coating roughness and coating adhesion of Cr N coating were analyzed by scanning electron microscope(SEM),XRD,surface roughness measuring instrument and scratch tester.When the abrasive blasting pressure is higher and the sand hardness is higher,the coating roughness is larger,and the film base bonding strength is smaller.After the dry sand blasting pretreatment of glass bead sand material under 2 bar pressure,the coating has the best comprehensive performance.The film-base adhesion of the coating is 78 N,the surface roughness of the coating is 0.369 μm,and the coating thickness is about 5 μm.The coating thickness is uniform,the coating surface is relatively smooth and dense,and there is no obvious hole structure.
