Abstract:
Rotavator has been most popularly used implement in agricultural field equipment. But the problem is that if abrasion conditions become too severe for ground engaging tools, the wearing of blades takes place. It adds the cost of equipment downtime and also it requires more frequent parts replacement. In this article, mainly focus on cost economics of electro-spark coated on rotavator blades. Electric spark coating (ESC) techniques was evaluated with tungsten carbide, stellite-21 and chromium carbide coating materials to improve the life of rotavator blade. The payback period of electro-spark coated tungsten carbide blade was found about 460 working hours or 1 year.
