Starved Lubrication

Five densities of laser-ablated micro-pits were fabricated onto medium-carbon steel surfaces based on the coupling effect of the biological surface. The effects of the surface textures on the wear behavior were investigated by sliding wear tests under starved lubrication. The results show that compared with the smooth sample, the biomimetic samples could effectively reduce friction and wear, and the tribological performance of the textured surfaces is closely related to the density of the bionic units. The equivalent stress distribution of the specimens was simulated by the finite element method. A uniform stress distribution is beneficial for effectively reducing the generation of wear cracks.

The tensile and fracture strength of a medium carbon steel containing 0.2wt%C were determined after austenitisation at 1100oC for 1 h and subsequent isothermal transformation at 700oC for 0.5, 2, 6 and 8 h. Only the specimens transformed for 0.5 and 2 h contained martensite and these were l5.67 and 7.20%, respectively. The maximum measured tensile and fracture strength were 91l and 852 MPa, respectively and these were obtained in the specimens with the most martensite (0.5 h). Although after austenitisation and subsequent isothermal transformation there was a loss in ductility, this was accompanied by a very significant improvement in tensile and fracture strength.

Compressive Residual Stresses

Introduction of compressive residual stresses on the fatigue-loaded components is one of the techniques followed to improve the fatigue life of industrial components. Oil jet peening is a surface modification process for the introduction of compressive residual stresses. A high-pressure oil jet is made to impinge on the surface to be peened. Preliminary studies were carried out on the medium carbon steel at the oil pressure of 50MPa. The compressive residual stress induced on the surface of unpeened and oil jet-peened AISI 1040 steel was 21MPa and 200MPa, respectively. Fully reversed cantilever bending fatigue behaviors of medium carbon steel in both under peened and unpeened conditions were evaluated at room temperature. Oil jet-peened specimens exhibited superior fatigue performance compared to the unpeened specimens. Fractographical analyses were carried out for specimens broken at several tested stress levels using optical microscope.
