摘　　要：介绍了镍磷镀层、渗氮层的性能和在油气田应用的情况,并针对镍磷镀层孔隙率高、镀层厚度不均等缺陷以及渗氮层易于剥落和产生微裂纹等问题提出了建议;对国外涂镀技术和国内石化行业应用渗镀材料的性能及成功应用情况进行了介绍;金属陶瓷涂层具有合理的显微结构、表面硬度较高、抗断裂性强、耐腐蚀和冲蚀性能优异;铝钛共渗钢具有良好的抗湿硫化氢腐蚀、抗氢致开裂(H IC)及硫化物应力腐蚀开裂(SSCC)的能力,其构件在湿硫化氢腐蚀环境的工业应用效果良好,并对渗镀涂层技术作为经济有效的防腐蚀措施将在油气田上得到推广应用进行了展望。The performance of Ni - P diffused coating and nitrogen diffused coating and their application oil ＆ gas fields are introduced. The defects of higher porosity and un - uniform thickness of Ni - P diffused coating, easy spalling of nitrogen diffused coating and micro cracking etc are analyzed and corresponding countermeasures are recommended. The overseas coating technologies, the performances of diffused coatings used in China petrochemical industry and their successful application are described. Metal ceramic coating which has good micro - structure, higher surface hardness and higher toughness against fractures have excellent corrosion resistance and erosion resistance performance. Al -Ti diffused coating offers a good anti wet H2S corrosion performance and excellent performance against hydrogen induced cracking （HIC） and sulfide stress corrosion cracking （SSCC）, which have been proven in commercial application. The diffused coating technology provides an effective economic corrosion prevention measure for the operation of oil and gas fields.
