Chamber arrangements, coating systems including chamber arrangements, and methods of coating workpieces in chamber arrangements and coating systems

A coating system, comprising:

• a chamber comprising
• an outer chamber with a hollow interior;
• an inner chamber sized and dimensioned for placement within the interior of the outer chamber, the inner chamber configured to support therein a workpiece, inner chamber further including a base defining a recess therein, wherein the workpiece is partially supported within the recess of the inner chamber and protrudes from the inner chamber and into the interior of the outer chamber;
• and
• an electrical connector seated in a wall of the outer chamber and fluidly separating the interior of the outer chamber from an external environment outside of the outer chamber, the electrical connector configured to provide electrical communication between the workpiece and a device located in the external environment outside of the chamber arrangement;
• a coating system precursor source fluidly coupled to the inner chamber;
• a coating system exhaust source fluidly coupled to the inner chamber and therethrough to the coating system precursor source through the recess defined within the inner chamber;
• and
• a coating system controller operatively connected to the coating system precursor source and disposed in communication with the workpiece, the coating system controller responsive to instructions recorded on a memory to form a coating onto the workpiece.

A method of forming a coating, comprising:

• at a chamber arrangement including an outer chamber with a hollow interior;
• an inner chamber sized and dimensioned for placement within the interior of the outer chamber, the inner chamber configured to support therein a workpiece;
• and an electrical connector seated in a wall of the outer chamber and fluidly separating the interior of the outer chamber from an external environment outside of the outer chamber, the electrical connector configured to provide electrical communication between the workpiece and a device located in the external environment outside of the chamber arrangement,
• supporting the workpiece within the chamber arrangement;
• forming a coating onto the workpiece while supported within the chamber arrangement;
• removing the workpiece from the chamber arrangement;
• and
• installing the workpiece with the coating formed thereon in an assembly or end item.
