Carbon Deposit Buildup Contamination

Carbon-buildup manifests as hard deposits from combustion and pyrolysis processes, which form tenacious layers on surfaces exposed to high-heat environments. This contamination, it distinguishes itself from softer residues by its dense, adherent structure that resists mechanical abrasion, particularly on steel and stainless steel where it embeds deeply, while on alumina or silicon carbide it appears more superficial yet persistent. Removal challenges arise from its thermal stability, influenced from substrate variations, but laser cleaning proves effective, as the beam vaporizes the buildup selectively without altering the underlying materials.
