Abstract
A piston for an opposed-piston engine has a thermal barrier coating on at least the piston crown. The piston, at least the piston crown, is made of titanium or a titanium alloy. The thermal barrier coating includes a bonding material and a ceramic material. The bonding material can be present in the thermal barrier coating at an interface of the thermal barrier coating and the bulk of the piston material. The ceramic material can be a high R-Value material. In particular, the piston with a thermal barrier coating can be an exhaust piston for an opposed-piston engine.
