Experimental Analysis of Tribological Properties of Heat Treated Graphitic Cast Irons
LATEST METHODS OF CONSTRUCTION DESIGN(2016)
摘要
The results of research investigations of tribological properties of heattreated cast iron with globular graphite are presented. The samples of investigated materials, including the reference material steel C45 were heat treated to the same hardness value. Tests were carried out on the experimental device with a linear reciprocal movement with variable speed using the Ball on Plate method. The device simulates real changed conditions in different environments of the tested contact pairs, such as sliding bearing, hinges, brackets and the like. The results of measured tribological properties of materials show that for practical applications and for specific environments and dynamic conditions the replacement of the original material C45 by isothermally tempered cast iron may be realistic.
