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.
