... that is susceptible to corrosive attack. Angle of Attack The angle of attack of slurry particles on a material determines, to a large extent, the role that the abrasives will play in corrosive wear. In straight pipelines where the flow of slurry particles is basically parallel to the walls of the pipe, little...

... that abrasives play in corrosive wear. In straight pipelines where the flow of slurry particles is basically parallel to the pipe walls, little damage to the underlying metal results from direct contact between the abrasive and alloy ( Ref 43 ). The abrasives, togehter with the solution, serve to slowly remove...
