【摘要】：目的研究TiAlN及TiAlSiN涂層的微觀結(jié)構(gòu)及力學(xué)性能,以及硬質(zhì)合金涂層刀具切削SUS304不銹鋼的切削性能及磨損行為。方法采用陰極電弧離子鍍技術(shù)在硬質(zhì)合金試片及銑刀上分別制備納微米TiAlN及TiAlSiN涂層。通過(guò)X射線熒光測(cè)量系統(tǒng)測(cè)量涂層的厚度,用掃描電鏡(SEM)觀察涂層表面形貌,用能譜儀(EDAX)分析涂層元素成分,用X射線衍射(XRD)分析涂層晶相結(jié)構(gòu),用納米壓痕儀表征涂層硬度,用洛氏硬度計(jì)定性測(cè)量涂層結(jié)合力,通過(guò)高速銑削試驗(yàn)探究涂層刀具的切削性能及磨損行為。結(jié)果 TiAlN及TiAlSiN涂層的厚度分別為3.32μm和3.35μm,表面致密、光滑,高分辨率(20 000×)下觀察到涂層表面有液滴、針孔及凹坑存在。Si元素促進(jìn)了Ti N(200)晶相的生長(zhǎng),晶粒尺寸減小,硬度增加。TiAlN及TiAlSiN涂層的顯微硬度分別為29.6 GPa及37.7 GPa,結(jié)合力分別滿足VDI-3198工業(yè)標(biāo)準(zhǔn)的HF3和HF1等級(jí)。在130 m/min的高速切削條件下,TiAlSiN涂層刀具壽命約為未涂層刀具的5倍,TiAlN涂層刀具的1.5倍。結(jié)論 Si摻雜制備的TiAlSiN涂層具有高的硬度及良好的抗粘附性,更適用于不銹鋼材料的高速切削加工。
[Abstract]:Objective to study the microstructure and mechanical properties of TiAlN and TiAlSiN coatings. The cutting performance and wear behavior of cutting SUS304 stainless steel with cemented carbide coated tools were studied. Methods Nano-micron TiAlN and T were prepared on cemented carbide test discs and milling cutters by cathodic arc ion plating. IAlSiN coatings. Measurement of coating thickness by X-ray fluorescence measurement system. The surface morphology of the coating was observed by scanning electron microscopy (SEM), the elemental composition of the coating was analyzed by EDAX, and the crystal structure of the coating was analyzed by X-ray diffraction (XRD). The coating hardness was characterized by nano-indentation instrument and the coating adhesion was qualitatively measured by Rockwell hardness meter. The cutting performance and wear behavior of coated tools were investigated by high speed milling test. Results the thickness of TiAlN and TiAlSiN coatings were 3.32 渭 m and 3.35 渭 m, respectively. Liquid droplets were observed on the surface of the coating under smooth and high resolution (20 000 脳). The crystal phase growth was promoted by the presence of .Si element in pinholes and pits, and the grain size decreased. The microhardness of TiAlN and TiAlSiN coatings were 29.6 GPa and 37.7 GPa, respectively. The binding force meets the HF3 and HF1 grades of VDI-3198 industry standard, respectively. Under the condition of high speed cutting of 130m / min. The life of TiAlSiN coated tool is about 5 times as long as that of uncoated tool. Conclusion the TiAlSiN coating prepared by Si doping has high hardness and good adhesion resistance, which is more suitable for high speed cutting of stainless steel.
