Abstract

본 발명은 각인을 용이하고 또한 선명하게 행할 수 있는 내연기관용 피스톤을 제공하는 것을 목적으로 한다. 알루미늄 합금제 피스톤본체(10)의 관면부(3)에 경질 알루마이트 처리에 의한 산화피막(8)을 형성한 내연기관용 피스톤에 있어서, 관면부(3)에 설정한 센터 가공보스(7)을 제거함으로써 상기 관면부(3)에 경질 알루마이트 미처리부(9)를 형성하였다.An object of the present invention is to provide a piston for an internal combustion engine that can be easily and vividly imprinted. In the piston for an internal combustion engine in which the oxide film 8 by hard anodizing is formed in the tubular part 3 of the piston body 10 made of aluminum alloy, the center processing boss 7 set in the tubular part 3 is removed. The hard alumite unprocessed part 9 was formed in the said tubular part 3 by this.
