“Laser transmission welding of ABS: Effect of CNTs concentration and process parameters on material integrity and weld formation”

This paper reports a study of the laser transmission welding of polymeric joints composed by two ABS (acrylonitrile/butadiene/styrene) sheets, one transparent (natural ABS) and the other absorbent (filled by different percentages of carbon nanotubes (CNTs)).

Ablación láser de recubrimientos de politetrafluoretileno (PTFE) aplicados sobre sustratos EN AW-5251

En la actualidad se utilizan diversos sistemas de eliminación de recubrimientos ricos en politetrafluoretileno (PTFE) sobre sustratos metálicos: granallado, pirólisis, procedimientos químicos y combinaciones de ellos, presentando todos ellos serias dificultades. En el presente trabajo se propone el uso de ablación láser para eliminar recubrimientos ricos en PTFE que previamente han sido aplicados en chapas de la aleación de aluminio magnesio EN AW-5251 H34.
