Investigation on the Erosion Behavior of Coated Piston in the Hydraulic Actuators

C. Senthilvel

In today’s world a huge number of process and techniques are done by the hydraulic systems. The system may undergo lot of erosion inside the cylinder and piston’s material due to the fluid used in cylinder. To reduce the erosion we are going to coat on piston’s crown with the ceramic coating. The Alumina Titania (Al2O3-TiO2)and the Tungsten Carbide-Cobalt carbide (WC-Co) are the two powders that is going to coat on the crown of the piston. The erosion is due to the actuation in the cylinder that is by the presence of foreign particles and temperature of the fluid which is used to actuate the cylinder. In order to improving the adhesion strength and with stand to high temperature during actuation. The D-gun spray technique has been employed on the mild steelto enhance its erosion behaviour of the mild steel. The improved coating on hydraulic pistons can be used in long lasting life than other material or coated parts.
