Abstract

Cynosure Cynergy Pulse Nd:YAG laser was used to

remove the painted material of 54 car coated substrate samples

A, B and C by manipulating the laser fluence energy (F), pulse

width (PW), repetition rate (RR) and beam size (BS). Alicona

IFM G4 was used to analyze irradiated crater depths and

obtained the optical surface micrograph which provides a

pattern of graphical illustration of the removal process. Average

temperature (ΔTAV) of car metal substrate was determined

during the laser paint removal process by using TC 6621

thermocouple. The maximum ΔTAV (

34.89 with BS 3 mm and 5 mm for sample A, 30.25 and 32.6 with

BS 3 mm and 5 mm for sample B whereas 28.16 and 33.15 with

BS 3 mm and 5 mm for sample C.
