Abstract:	Parts such as the rotors and stationary blade holders that are exposed to highly corrosive geothermal steam are particularly susceptible to general corrosion and erosion corrosion, which may lead to the problem of dropout of the blades. A thermal spray coating technology for the parts surface has been developed. Basic tests in the R&D laboratory like hardness, porosity and corrosion tests were conducted at R&D Lab of Metallizing Equipment Company Pvt. Ltd to establish a practical technology using a HVOLF (high-velocity oxygen-Liquied fuel thermal spray coating) process to apply a carbide coating by MJP-5000 (MEC make). HVOLF coating was applied on the 8th stages blades of the turbine rotor at Metallizing Equipment Company Private Limited Company, Jodhpur.
