Abstract
A system for selectively carbonizing a polymer coating on a substrate includes a laser, a memory, and a controller. The memory stores data associated with at least one characteristic of a substrate having a coating that includes a polymer material. The controller is operatively connected to the laser, and is configured to control the laser based on the data such that, in an open-air environment, an interaction between the laser and the polymer material carbonizes a portion of the coating, but does not sustain combustion of the polymer material. A method of producing an article with a selectively carbonized coating includes controlling a laser system such that interaction between a laser and a polymer material forming a coating on a substrate carbonizes a portion of the coating, but does not sustain a combustion of the polymer material in an open-air environment.
