Abstract:
This study aimed to improve the surface properties of grey cast iron (GG25) that used in the manufacturing of gates of water regulators. Taguchi/ANOVA (Analysis of Variance) technique was used to design the experimental of the coating process and erosion – corrosion test, microhardness for coated and uncoated samples and particle size distribution test for glass sand that use in erosion test also done. The surface hardness of coated grey cast iron (GG25) can be enhancing about 90% and the erosion resistance was increased by 67%.
