    Investigations on the effect of ball burnishing parameters on surface hardness and wear resistance of HSLA dual-phase steels
    (2008) Rao, D.S.; Hebbar, H.S.; Komaraiah, M.; Kempaiah, U.N.
    Surface finish has a vital influence on most functional properties of a component like fatigue life, wear resistance, corrosion resistance, etc. This has given birth to processes such as lapping, honing, burnishing, etc. Burnishing is a fine finishing operation involving the cold working plastic deformation of surface layers to enhance the surface integrity and the functional utility of a component. The present study has been carried out to establish the effect of burnishing parameters viz. feed rate, speed, force, ball diameter and lubricant on surface hardness, and wear resistance of HSLA dual-phase steel specimens. The result indicates that burnishing parameters have significant effect on the surface hardness and wear resistance.

    Studies on the effect of ball burnishing parameters on surface hardness of HSLA dual-phase steels using factorial design
    (2008) Rao, D.S.; Hebbar, H.S.; Komaraiah, M.; Kempaiah, U.N.
    Burnishing is used increasingly as a finishing operation which gives additional advantages such as increased hardness, fatigue strength and wear resistance. Experimental work based on 34 factorial design was carried out to establish the effects of ball burnishing parameters on the surface hardness of HSLA dualphase steel specimens. Statistical analysis of the results shows that the speed, feed, lubricant and ball diameter have significant effect on surface hardness.

    Surface hardening of high-strength low alloy steels (HSLA) dual-phase steels by ball burnishing using factorial design
    (2007) Rao, D.S.; Hebbar, H.S.; Komaraiah, M.
    Burnishing is used increasingly as a finishing operation which gives additional advantages such as increased hardness, fatigue strength, and wear resistance. Experimental work based on 34 factorial design was carried out to establish the effects of ball burnishing parameters on the surface hardness of high-strength low alloy steels (HSLA) dual-phase (DP) steel specimens. Statistical analysis of the results shows that the speed, feed, lubricant and ball diameter have significant effect on surface hardness.
