Oil sands operations may give rise to various corrosion risks such as pitting corrosion crevice corrosion microbiologically induced corrosion and abrasion-corrosion. These risks are mainly related to the chemical composition of the slurry and the presence of abrasive particles or rocks. That is why the corrosion resistance is a critical parameter that has to be taken into account for material choice to avoid regular maintenance of the process equipment.This paper focuses on the abrasion-corrosion resistance of various stainless steels and wear resistant carbon steels. The abrasion-corrosion tests were conducted by means of an innovative test method in environments containing chlorides in a pH range from 3 to 10. These tests were combined with electrochemical techniques in order to study the interaction between the surface of the materials and the corrosive solution during the tests.The results show that wear resistant steels are more resistant to abrasion-corrosion than stainless steels in environments containing a low amount of chlorides when the pH is basic. On the contrary in more corrosive environments wear resistant steels are susceptible to corrosion. In such environments duplex stainless steels are more resistant to abrasion-corrosion and can be considered as excellent candidate materials for various applications like piping systems for instance.

This paper aims to present a novel class of pipeline protective lining materials that provide erosion-corrosion resistance combined with negligible wear to spray equipment. These coatings have been formulated with a blend of thermoplastic fillers rather than the traditional ceramic fillers used for erosion resistance.
