Refinery process vessel internal walls and related piping exposed to aggressive fluids containing hard, solid particles such as catalyst particles are subject to both erosion and corrosion. The protection of these vessels and piping against erosion and corrosion induced material degradation especially at high temperatures is a technological challenge. The life span of the state-of-the-art monolithic refractory liners currently in use is limited by excessive mechanical recession of the liner from high velocity solid particle impingement, mechanical cracking and spalling. In order to overcome this challenge, advanced TiB2-stainless steel cermets were designed for high fracture toughness and the chemical stability required for the long term service. In this paper, we present a class of TiB2-stainless steel cermets exhibiting an order of magnitude higher erosion resistance and superior corrosion resistance compared to state-of-the-art materials.
