Abstract The effect of laser modification of the surface on the value of the coefficient of elasticity, hardness, coefficient of friction and the amount of wear of the counter body when testing products made of a deformable titanium alloy was investigated. It was found that the indicators of hardness and wear resistance of a titanium alloy depend on the modes of laser modification. These dependencies are extreme in nature, they have maxima and minima. The quantitative values of hardness and wear resistance indicators for the specified material before and after laser treatment of its surface in various modes are given.

Laser Surface Modification

Titanium alloys are widely utilized in laser heating applications. However, it has poor optical properties due to low laser energy absorption. Nevertheless, a higher energy absorption can be realized by modifying the surface profile through increasing the surface roughness. In this present work, the laser surface modification (LSM) process was carried out to increase the roughness on surface of Ti6Al4V titanium alloy. Subsequently, the surface characterization and surface roughness were analysed by using the 3D optical microscope. The effect of laser power on the increment of surface roughness was investigated. It was revealed that an increase in laser power during LSM process could increase the surface roughness. The result shows that, the surface roughness of titanium alloy increased 27 times when modified with the highest laser power (27W) compared to the gritted surface. Furthermore, the modified surface by LSM will be heated using laser radiation in order to analyse the effect of surface roughness towards laser heating temperature. Depending on the value of the power during laser heating, the maximum temperature measured could be increased 27% corresponding to a gritted flat reference surface.

Laser Surface Modification

The aim of this study was to investigate the effect of the surface condition of the coulters of a Poznaniak mechanical seeder working in a sand medium on their abrasive wear resistance. Two types of coulter flap surface treatments were performed. The first treatment method was flame spraying, performed with the use of Eutalloy 10112 powder and other method was laser surface modification consisting in remelting a piece of the coulter flap tip by means of TRUMPF’s CO2 molecular laser. The study involved the use of a purpose-built laboratory test stand dedicated to testing wear in a sandy medium. The study revealed that surface treatment changes surface microstructure and thus improves its hardness by [Formula: see text] to 3 times, which translates into two- to six-fold improvement in wear resistance per hectare of cultivated field. Laser surface modification is more economical than thermal spraying and that the coulter flap surface area modified by thermal spraying was much greater than in the case of laser remelting, and finally that the average wear measured as a weight loss of tested coulters was comparable, one can conclude that in the analyzed context laser surface modification will probably prove more efficient than flame spraying. The study showed that there exist ready-to-use technologies for improving operational performance and delaying terminal wear.
