Abstract
A method for applying a sulfonation treatment to a thermoplastic part includes installing a gas sulfonation assembly on one or more surfaces of the thermoplastic part by forming a vacuum bag on the one or more surfaces. The vacuum bag forms a sealed cavity between the vacuum bag and a treatment portion of the one or more surfaces. The method further includes drawing a vacuum in the sealed cavity with the gas sulfonation assembly, directing a sulfonating gas into the sealed cavity with the gas sulfonation assembly to sulfonate the treatment portion, removing the sulfonating gas from the sealed cavity with the gas sulfonation assembly, removing the gas sulfonation assembly from the thermoplastic part, applying a neutralizing agent to the treatment portion, and applying at least one coating to the treatment portion.
