The Effect of Carbides Morphology on Tribological Behaviour of Ni-Hard 4 Cast Irons
In this research the effect of volume and morphology of eutectic carbides on tribological behaviour of Ni-Hard 4 cast irons have been investigated. Therefore, as a result of the fact that the carbon content effects the carbides morphology of Ni-hard cast irons, the chemical compositions of five different specimens were kept constant with the exception of the carbon content, which was varied fro...
متن کاملGraphite Phase Formation in Al Alloyed Ductile Irons
The influence of aluminum, within the range of 0.08 - 6.16 wt.%, on the microstructure and hardness of as-cast ductile cast iron has been studied. A number of irons of different composition have been made by green sand casting and gravity die casting of appropriate design to provide the experimental materials. It has been found that Al addition and higher cooling rates in permanent mould castin...
متن کاملDelamination Wear Mechanism in Gray Cast Irons
An investigation of the friction and sliding wear of gray cast iron against chromium plated cast irons was carried out on a newly constructed reciprocating friction and wear tester. The tests were the first to be done on the test rig under dry conditions and at the speed of 170 cm/min, and variable loads of 20-260 N for a duration of 15 min. to 3 hours. The gray cast iron surfaces worn by a pro...
متن کاملA RESEARCH ON THE CALCULATION OF GRAPHITIZATION ABILITY OF GRAY CAST IRONS
In this research the relationship between graphitization ability and the carbon equivalent (CE %) of a cast iron have been investigated. The first series of moulds were cast at CE of 3.2% and pouring temperature of 1350°C. The other moulds were cast at different CE% with varying Si content. The graphitization ability( c ) was calculated using the thermodynamics aspects of graphitization and CE%...
