Abstract:
Exemplary pistons and methods are disclosed. A method may include depositing a scuff and seizure resistant material via a thermal spray method on the surface of a piston pin bore used in internal combustion engines. Exemplary pistons may have a crown and a skirt. The piston crown may define a combustion bowl and a ring land extending circumferentially around the combustion bowl, the skirt supporting the crown, the skirt including a pair of pin bosses, the pin bosses each defining a pin bore configured to receive a piston pin, each pin bore defining a pin bore surface extending circumferentially about the piston pin bore, the bore surface formed of a first material. The method may further include applying a coating comprising at least a second material different from the first material to the pin bore surfaces using a thermal spray process.
