DEFINITION

Classification: 427/596

Laser or electron beam (e.g., heat source, etc.):

(under subclass 595) Processes wherein laser or electron beam is utilized as a heat source to assist in the deposition of the coating material.

(1) Note. Processes wherein a narrow beam of coherent light (light amplification by simulated emissions of radiation) is utilized to assist in the deposition of the coating material are found here.

(2) Note. Processes wherein a narrow stream of electrons moving in the same direction under the influence of an electric or magnetic field is utilized as a heat source to assist in the deposition of the coating are found here.
