该课题是冶金部教育司下达给武汉钢铁学院的研究课题,由材料系完成。课题组对原有的直流等离子体气相沉积装置进行了改装,用金属、有机化合物进行PCVD涂层,使刀具寿命提高2～4.5倍。另外,还用等离子喷涂法在耐热钢基体上涂复陶瓷,使耐热钢在1250℃下氧化速率由9.38g/m~3·h降低至6.086g/m~3·h。这样,用无镍耐热钢制造高温耐氧化部件,从而使成本降低50％,整体装置和工艺水平达到国内先进水平,具有推广应用价值。
The subject is the Ministry of Metallurgical Education Division issued to the Wuhan Iron and Steel Institute of the research topic, completed by the Department of Materials. Task Force to the original DC plasma vapor deposition device was modified with metal, organic compounds PCVD coating, the tool life increased by 2 to 4.5 times. In addition, ceramic was also coated on the heat-resistant steel substrate by plasma spraying, so that the oxidation rate of the heat-resisting steel decreased from 9.38g / m ~ 3 · h to 6.086g / m ~ 3 · h at 1250 ℃. In this way, the use of high temperature resistant nickel-free heat-resistant steel components, so that the cost reduced by 50%, the overall level of equipment and technology to reach the domestic advanced level, with the promotion and application value.
