| Abstract | ||
| This work shows the evaluation process of the surface temperature by using heat sink (thermocouple) technique from type Alumel-Chromel (Ni-Al/ Ni-Cr) and to study its effect on the dry sliding wear characteristics of a bainitic ductile cast – iron. These characteristics represented with wear rates and coefficient of friction, which evaluated by using Pin on Disc machine under different laboratories conditions involved four applied normal loads (10, 20, 30, 40)N and three linear sliding speeds (1.4, 2.2, 3.0)mm/sec at room temperature. The present work shows the dry sliding wear characteristics and variables depend on the surface temperature generated during wear test. So, it can’t ignore these effects during the service. In addition to, it must be avoided using loads range (30-40)N and temperature range (310-360)Cͦ during practical applications it may be used this alloy within these ranges, because of both the two ranges may be led to occur severe wear of the bainitic ductile cast – iron surfaces with other counter surfaces of its working conditions. | ||
