Abstract
A trailer hitch assembly includes a hitch plate and a locking mechanism. The hitch plate includes a throat for receiving a kingpin of a trailer. The locking mechanism locks the kingpin in the throat and includes a pair of lock jaws whose lock jaw contact surface, which contacts the kingpin, is treated with an alloy obviating the need for a lubricant while maintaining the wear life of the pair of lock jaws.
