【摘要】：用多弧離子鍍膜技術(shù)結(jié)合熱擴(kuò)散成功制備了高硅鋼材料。研究了在不同擴(kuò)散溫度下合金的結(jié)構(gòu)、形貌以及硅擴(kuò)散深度。X射線衍射(XRD)測(cè)試表明,在經(jīng)過(guò)高溫?zé)崽幚砗髽悠繁韺泳鶠棣?Fe體心立方結(jié)構(gòu)。硅擴(kuò)散依賴于表層Fe3Si的結(jié)構(gòu)的形成,場(chǎng)發(fā)射掃描電鏡結(jié)合X射線能譜(FE-SEM,EDS)檢測(cè)顯示:在經(jīng)過(guò)1200℃真空熱處理后樣品斷面硅質(zhì)量分?jǐn)?shù)從4.6%至5.1%不等,而顯微硬度HV測(cè)試值為2800 MPa,進(jìn)一步印證了能譜測(cè)試的準(zhǔn)確性。
[Abstract]:High silicon steel was successfully prepared by multi-arc ion plating combined with thermal diffusion. The structure and morphology of the alloy at different diffusion temperatures and the X-ray diffraction (XRD) measurements of silicon diffusion depth show that the surface layer of the alloy is 偽 -Fe body-centered cubic structure after high temperature heat treatment. Silicon diffusion depends on the formation of surface Fe _ 3Si structure. The results of field emission scanning electron microscopy (SEM) and X-ray energy dispersive spectroscopy (EDS) show that after vacuum heat treatment at 1200 鈩，
