Wear and corrosion are problems prevalent in the industrialized world. One way to overcome this matter is the process of coating with a thermal spray coating. The coating process is categorized into two processes based on the heat source, i.e., combustion and electric. One example of combustion process is the high-velocity oxygen fuel (HVOF). The HVOF system which is operated manually has been studied in previous works. Computerized HVOF system is developed and manufactured in this study to improve reproducibility of coating and safety of operator. ATMega16 microcontroller was connected with several sensors (oxygen mass flow controller, nitrogen mass flow controller, propane mass flow controller, and pressure sensor), and Visual Studio.Net 2013 was used to create a graphic user interface (GUI). Based on test results obtained, it was found that the GUI successfully communicated using serial communications and could access the input/output (I/O) required by the microcontroller. Combinaton of gas mass flow controller and pressure sensors result in precise control of oxy-fuel combustion process.

The synthesis of polymers with controlled molecular and structural parameters is challenging due to the required purity of the chemicals and the exclusion of protic impurities and oxygen in particular in the case of an anionic process as shown here.
