Slurry erosion behaviour of Ni-Hard under various impact angle and speed

To Study wear analysis of slurry pump with an experimental condition is an economically costly and lengthy process. Therefore, wear study can be done on various laboratory tests such as Slurry pot tester, Coriolis wear tester, Whirling arm wear test device, particle impact jet test. To analyze of erosion wear rate of slurry pump material in different operating conditions is performed on slurry pot tester. In the latest pump the Ni-Hard is widely used material in the slurry transportation. The one of the major application of slurry pump made from Ni-Hard is in Thermal power plant for ash slurry transportation. In this paper an experimental work has been carried out to find the effect of impact angle and particle impact speed at 20% w/w slurry concentration of sand on the wear rate of the Ni-Hard material. From the experimental results it is found that as particle velocity increases erosion wear rate of the material is increases. It was also found that the erosion of the material increases with impact angle till 30° then the erosion of material decreases gradually.
