| Summary: | In line with the Indonesian government's policy on national electrification plans by developing a 35,000 MW power generating facility which was started in 2014, the need for high temperature resistant materials becomes the demand for the application, moreover materials dedicated to engineering equipment such as boilers as a steam producer to drive the Coal-Fired Power Plant (PLTU) turbine. The operational challenge of materials at high temperatures becomes serious, especially as the use of low quality coal as fuel in the combustion system creates degradation problems on tube surfaces such as erosion and corrosion thereby limiting boiler tube life. Thermal spray coating technologies for high temperature operations have been developed with the aim of protecting boiler tubes from aggressive environments, improving thermal efficiency, and reducing time losses from damage. High Velocity Oxygen Fuel (HVOF) thermal spray technology is one of the recommended methods to be used in boiler tubes at Coal-Fired Power Plant (PLTU). The following works discusses the creep behavior within elevated temperature and static loading of SUS 304 with thermally sprayed coating of NiCr matrix composite using HVOF deposition method. |
