Abstract
⺠Carbonaceous deposits on piston surface were removed by nanosecond pulse laser cleaning. ⺠Thick and thin layers of stubborn contaminants were deposited non-uniformly on the surface. ⺠Main constituents of the deposits were Fe3C, Fe3O4, possibly FeOOH, oxygenated hydrocarbons and carboxylates. ⺠Fe3C was removed completely and oxygenated hydrocarbons as well as carboxylates were reduced significantly after laser cleaning. ⺠Oxidation and melting effect took place during laser processing.
