The Surface Free Energy after Laser Beam Treatment

Abstract:

Recently the laser beam treatment is more and more in common practice. The fields of use are very diverse. One of these fields of activity is removing of pollutions from a surface and preparation of it before the next stage of treatment. In the paper are presented the results of experimental research which were conducted in the aim of assessment of effects after cleaning of AISI 4130 steel by laser beam. The indicator of process quality was surface free energy (SFE) which is well known indicator in the operation where adhesion is very important. To its assess the measurement of wettability angle is required. After the experiment the results show that it is possible to improve the energetic state of the surface, thus the better preparing of surface before activity when the good adhesion properties are needed than in the case of traditional manner of treatment.
