The method of claim 4, wherein the chamber wall comprises boron nitride. 6. The method of claim 1, wherein the chamber wall comprises a substantially tubular shape. 7. The method of claim 1, wherein a stainless steel sheath is coupled to the faceplate and around the chamber wall. 8. The method of claim 1, wherein the faceplate is configured to be coupled to the chamber wall prior to being coupled to the plasma gun, thereby allowing the faceplate and the chamber wall to be coupled to the plasma gun and de-coupled from the plasma gun as a single unit. 9. The method of claim 8, wherein the faceplate, the chamber wall, and the plasma gun are configured to be coupled together using one or more threaded fasteners. 10. A plasma gun system comprising: a plasma gun comprising an outlet, wherein the plasma gun is configured to generate a plasma stream and provide the plasma stream to the outlet;a plasma gun extension assembly configured to be coupled to the plasma gun, wherein the plasma gun extension assembly comprises an extension chamber, the extension chamber having an interior diameter defined by a chamber wall and being configured to receive the plasma stream from the outlet of the plasma gun and to enable the plasma stream to expand upon entering the extension chamber; anda faceplate configured to be coupled to the plasma gun using one or more fasteners and to the chamber wall using one or more fasteners, wherein the face plate comprises a port disposed on the faceplate and a channel disposed within the faceplate that is fluidly coupled to the port, the port being configured to introduce a powder to the expanded plasma stream at a location outside of the plasma gun. 11. The system of claim 10, wherein the faceplate comprises a circular ring shape and the outlet of the plasma gun is aligned with the center of the faceplate to enable the plasma stream to pass the faceplate and flow into the extension chamber. 12. The system of claim 10, wherein the faceplate comprises copper. 13. The system of claim 10, wherein the chamber wall comprises a ceramic material. 14. The system of claim 10, wherein the chamber wall comprises boron nitride. 15. The system of claim 10, wherein the chamber wall comprises a substantially tubular shape. 16. The system of claim 10, wherein a stainless steel sheath is coupled to the faceplate and around the chamber wall. 17. The system of claim 10, wherein the faceplate is configured to be coupled to the chamber wall prior to being coupled to the plasma gun, thereby allowing the faceplate and the chamber wall to be coupled to the plasma gun and de-coupled from the plasma gun as a single unit. 18. The system of claim 17, wherein the faceplate, the chamber wall, and the plasma gun are configured to be coupled together using one or more threaded fasteners.
