Resumo: | Hydrophobic coating with ceramic, as nanotechnology, is widely used to protect metal in different industries, but it has not yet tested with agricultural tools. Nickel chrome plating is defined and used process to protect metals too, but it has a common use. So, this work discusses the effect of two types of coating techniques on wear reduction on normal chisel plough shares. First coating technique was using nanotechnology inform of SI14-200 micron (0.2 mm) high density hydrophobic and ceramic coating. Second coating technique was using the galvanizing process by treating the shares with nickel chrome plating. Both techniques were applied for chisels’ shares made from medium carbon steel C-45. All treated shares were operated for 40, 80 and 120 hours to observe wear characteristics and it was compared to the control untreated shares. Weight loss of chisel plough shares and dimensional wear loss percentages were recorded as dependent parameters. Shares treated with hydrophobic and ceramic coating gave promising results during first 40 working hours with average weight loss values of 0.49 % because of the lower abrasive action and friction of coated materials. While, weight loss values obtained by using chisel plough shares without treatment were the highest at all working hours. Control chisel shares gave the highest differences in dimensions in mm. The lowest differences in dimensions obtained when using shares treated with hydrophobic and ceramic coating, where, average differences between original and final dimensions at six different points along with shares width and length were 1, 1, 2, 2, 2, 1 mm when using the shares for 40 working hours. At higher working hours, 80 and 120 h, the better values either for weight loss or for differences in dimensions achieved by shares treated with nickel chrome plating. Cost of treating shares with nickel chrome plating is higher than using hydrophobic and ceramic coating but it gives long working life, lower required drawbar pull forces and better performance for chisel shares.
