以06Cr18Ni11Ti奥氏体不锈钢、14Cr17Ni2马氏不锈钢、00Cr22Ni5Mo3N双相不锈钢作为钻井机械设备材料,利用电弧离子镀技术制备TiN、TiBN、TiBN/TiN涂层,选取包括物理性能、耐阴极剥离性能及耐浸泡性能等作为设备耐腐蚀性能评价指标,模拟海水气溶胶腐蚀环境,研究3种不锈钢材料在海水浸泡、5%NaCl盐雾腐蚀和老化腐蚀下的耐腐蚀性能.试验结果表明:钻井机械设备材料为00Cr22Ni5Mo3N双相不锈钢,并镀TiBN/TiN涂层时,其耐腐蚀性能最突出.
Corrosion Resistance Evaluation for Offshore Oil Drilling Machinery
06Cr18Ni11Ti austenitic stainless steel,14Cr17Ni2 Marstenitic stainless steel,00Cr22Ni5Mo3N duplex stainless steel were adopted in manufacturing drilling machinery,including making use of arc ion plating technology to prepare TiN,TiBN and TiBN/TiN coating,and selecting physical properties,cathodic stripping resistance and immersion resistance as the evaluation indexes of equipment corrosion resistance to investigate their corrosion resistance under seawater immersion,5%NaCl salt spray corrosion and aging cor-rosion.The test results show that,the drilling machinery boasting of 00Cr22Ni5Mo3N duplex stainless steel and coated with TiBN/TiN coating has outstanding corrosion resistance.
