A system and method are disclosed. The system includes an assembly with a base, and a coating disposed on the base, wherein the coating has a density greater than 98 percent of a theoretical density of the coating, and a dilution less than 0.5 volume percent of the coating. In an embodiment, the assembly includes a shaft and a journal bearing coupled to the shaft, wherein at least one of the shaft and the journal bearing includes the base. In another embodiment, the assembly includes a valve coupled to a valve seat, wherein at least one of the valve and the valve seat includes the base, and the base includes a plurality of dimples, the coating disposed on at least some dimples. The method is for disposing a coating on a base of the assembly using a friction surface process.
