“…This method offers several advantages, including: absence of mechanical contact or tool wear, reduction of secondary pollutants (exhaust abrasives or chemical solutions), low energy consumption, greater flexibility of use and the possibility to work both small and large batches. Examples of applications of this process in paint or coating removal are reported in Schmidt et al [20], Barletta et al [21], Leone et al [22], Singh et al [23], Arif and Kautek [24], Chen et al [25].…”

“…Explosive removal of coating followed by evaporation is evident by the absence of material redeposition once the process is completed. 11,[16][17][18][19][20] Latest developments in cutting tool de-coating have led to a renewed interest in de-coating studies. Table 1 presents a summary of the studies that investigated the use of lasers for de-coating various substrate types.…”

“…For instance, in cleaning optical elements using chemical cleaning methods, re-deposition of impurities from the chemical solution could re-contaminate the cleaned surface and change the surface topography of the element itself. 11 These factors create an urgent necessity to develop more compatible methods for the cleaning and de-coating processes. In manufacturing industry, the capability of this new de-coating process is significant as it could facilitate re-grinding and recoating of drills thereby improving economic aspects.…”

Laser irradiation de-coating is a promising new approach for effective coating removal of cutting tools. While this method has demonstrated feasibility for conventional coatings, its use and efficacy on lubricant coating is however yet to be ascertained. This paper reports on the results of excimer laser de-coating of hard DLC from DLC-coated tungsten carbide (WC) substrates. A range of fluence and pulse was studied to evaluate the effectiveness of the de-coating process. Result shows that laser parameters of 7 J/cm2 fluence, 400 pulse and 25 Hz frequency were found to yield optimum results in removing hard DLC coating of 3.2 μm thickness from WC substrates. The experimental work indicated successful laser de-coating of hard DLC coating without noticeable damage to the WC substrate. The capability of this new de-coating process is significant in the aerospace industry as it could facilitate re-grinding and recoating of drills thereby improving economics of manufacturing. The process windows could also be applied in the removal of DLC from other cutting tools and applications.

“…Since different materials have different absorption rates for lasers, different materials have different optimal cleaning thresholds. The absorption rate of common metals for lasers is shown in Figure 1 [18][19][20]. For aluminum alloy, when the laser wavelength is 1064 nm, the absorption rate of laser to the substrate is higher.…”

Investigation on the Surface Properties of 5A12 Aluminum Alloy after Nd: YAG Laser Cleaning

The surface of the aluminum alloy is prone to oxidation, which in turn affects the quality of the weld. The 5A12 aluminum alloy was cleaned by acousto-optic Q-switched diode-pumped Nd:YAG laser and the effects of different laser powers and different cleaning speeds on the surface roughness, microstructure, element content, microhardness, residual stress and corrosion resistance of aluminum alloy were investigated. The results show that when the power is 98W and the cleaning speed is 4.1 mm/s, the effect of Nd: YAG laser on the removal of oxide film on 5A12 aluminum alloy surface is the most effective. After laser cleaning, the smoothness and strength of aluminum alloy surface can be effectively improved. However, as a major element in 5A12 aluminum alloy, the content of magnesium decreased. At the same time, the residual tensile stress was generated on the surface of the aluminum alloy after cleaning, and the corrosion resistance slightly decreased.
