Oil production and refining environments pose a very severe wear and corrosion environment. Material designers are challenged with the need to design and develop materials that combine a high corrosion resistance with very good wear resistance. Coupled with that is the need for these materials to meet requirements, such as, fracture toughness and resistance to sulfide and chloride stress corrosion cracking. Often times, increasing the resistance to wear compromises the corrosion and welding characteristics. This paper covers a variety of material developments that aim to address the twin problems of wear and corrosion. The paper covers the alloy design fundamentals and discusses the pertinent wear properties and general corrosion resistance compared to traditional wear resistant materials. Proven applications, with particular reference to petroleum and petro-chemical areas are discussed. Potential applications are also cited.
