Surface effects of corrosive media on hardness, friction, and wear of materials
An investigation was conducted to examine the hardness, friction, and wear behavior of MgO, Fe, and Ni exposed to corrosive media. The results indicate that MgCl sub 2 films are formed on cleaved MgO surfaces from their interactions with HCl-containing solutions. The MgCl sub 2 films soften the MgO...

| Summary: | An investigation was conducted to examine the hardness, friction, and wear behavior of MgO, Fe, and Ni exposed to corrosive media. The results indicate that MgCl sub 2 films are formed on cleaved MgO surfaces from their interactions with HCl-containing solutions. The MgCl sub 2 films soften the MgO surfaces and cause high friction and considerable deformation. Neither the p H value of nor the immersion time in NaOH-containing, NaCl-containing, and HNO sub 3 -containing solutions influences the hardness of MgO. NaOH forms a protective and low-friction film on Fe surfaces at concentrations of NaOH > 0.01N . NaOH at concentrations of 0.001-20N forms a protective film on Ni that provides low friction and reduces damage due to wear. In ordinary water the Ni surface sustains considerable wear damage. 22 ref.--AA |
