Research on High-Temperature Corrosion-Resistance Performance of Exhaust Pipe of Heavy Duty Vehicle


Article Preview

The exhaust pipe of a heavy duty vehicle, due to its harsh operating environment, is subject to corrosion caused by high temperature oxidization, chlorination and sulfuration, therefore, corrosion occurs very easily, which affects normal operation of the engine. The exhaust pipe of the engine can be protected by means of electro-thermal explosion spray-coating technique. The corrosion-resistant ability of coating in high temperature environment is surveyed respectively. The micro organizational structure of coating is studied in combination with SEM, EDS and other tests to search for corrosion-resistant principle of the coating in an attempt to improve the corrosion-resistance of the exhaust pipe of the engine.
