The dry adhesive wear behavior of 1 060 and 1095 steels using pin on wheel wear test rig at room temperature under different wear conditions has been studied. The prepared specimens are normalized to make sure that all specimens are in the same conditions.
'The objective of this research is to study the effect of operating parameters such as rotating speed , normal load and sliding time and their interaction on the wear behavior using regression analysis. Detailed data obtained were used to develop equations to describe the wear rate of steels. The wear losses of the specimens were expressed in terms of simultaneous contribution from the effects of rotating speed , normal load , sliding time and their interaction.
By applying the parameters such as rotating speed , normal load , and sliding time,it is observed that certain effects on the wear behavior of two types steel , the 1060 steel , sliding time is the main factor, followed by normal load and rotating speed . However ,for the 1095 steel , rotating speed i s the main factor, followed by normal load and sliding time.
From results, it was concluded that the wear behavior of these steels and the effects of these parameters on the wear depend on the physical and mechanical properties of these types of steels.

In this paper, dry sliding wear and corrosion behavior of Cu + 13wt% Al + 3.8 wt% Ni was prepared by powder metallurgy. Dry sliding wear has been studied based on pin on disk at constant velocity and constant sliding distance .Corrosion behavior in 5 wt% NaOH solution based up on potentiostatic ( Tafel ) has been presented for base shape memory alloy ( Cu + 13% Al + 3.8 % Ni ) in two cases austenitic and martensitic phase state . Further more , the effect of Fe additions as ( 0.4 , 0.8 and 1.2 wt% ) on the sliding wear and corrosion behavior of
base alloy has also been studied .It is clear that Cu Al Ni shape memory alloy in martensitic state has more wear resistance than in austenitic structure . Also , corrosion resistances are better than in martensitic structure because the alloy has corrosion current density as 336.45 μA/cm2 in martansitic where as the corrosion current density is 633.62 μA/cm2 in austenitic structure . Further more , when the
iron content increases , wear and corrosion rate increase too .
