The shovels used in cultivators are largely manufactured by the small scale industries. Due to improper material and surface hardening treatments, the quality of shovels does not conform to the Bureau of Indian Standards resulting in high wear rates and reduced life. It leads to Farmer's complaint about the high wear rate of tiller shovels and agricultural equipments in dry land areas. This high wear rate increases the cost of part replacement, downtime and labour.
The objective of this study was to improve the wear resistance of tiller shovel with four different hard facing electrodes (Va, Co, B & Ti). Shield Metal Arc welding was used for depositing the layers of hard facing alloy on tiller shovels. Rubber wheel abrasive test apparatus was used for Comparative wear tests on a regular tiller shovel and four hard faced tiller shovels, where the effect of hard facing alloys on the extent of wear and the wear characteristics of shovels were examined. In this study wear rate and hardness of regular tiller shovel and hard faced tiller shovels, where studied. Regular tiller shovels gives the maximum wear and reduced 3 to 5 times with the help of hard facing alloys.
