The Impact

The erosion–corrosion (EC) and pure erosion of commercially pure titanium have been investigated in a 3.5% sodium chloride solution containing 10, 30, and 60 g/l SiO2 particles with an average size of 318 μm. The tests were performed at impact velocities of 4, 6, and 9 m/s under two impact angles of 40 deg and 90 deg. Polarization technique was used to study corrosion behavior of the material during erosion–corrosion. The eroded surfaces were examined by a scanning electron microscope (SEM) and a surface profilometer. The pure erosion, corrosion, and erosion–corrosion rates increased as impact velocity and sand concentration increased. The corrosion rates of the eroding surfaces under a normal impact were lower than those at an impact angle of 40 deg. The S/T ratio, i.e., the ratio of synergy to erosion–corrosion rates was about 80% at an impact velocity of 4 m/s, which indicated the high effect of the electrochemical corrosion on the degradation of CP-Ti at low velocity. The S/T ratio decreased to 30% and 15% at the impact velocities of 6 and 9 m/s, respectively. The S/T ratio was also decreased with increasing sand concentration indicating a greater role of mechanical degradation upon the erosion–corrosion rate in the concentrated slurries.

Minimum Yield

Abstract RMI 0.2% Pd is a grade of commercially pure titanium to which up to 0.2% palladium has been added. It has a guaranteed minimum yield strength of 40,000 psi with good ductility and formability. It is recommended for corrosion resistance in the chemical industry and other places where the environment is mildly reducing or varies between oxidizing and reducing. The alloy has improved resistance to crevice corrosion at low pH and elevated temperatures. This datasheet provides information on composition, physical properties, elasticity, tensile properties, and bend strength. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Ti-74. Producer or source: RMI Company.
