Abstract
Laser surfacing with hard metal powders presents a new and significant alternative of surfacing thin layers to arc processes as plasma arc and thermal spraying employing the high-temperature and/or high-velocity processes. Laser features some advantages over both these methods. Existing research works and some industrial application of laser surfacing with NiCrSiB-based powders with hardness up to 62 HRC and with additions of carbides, mainly WC, have shown the vitality of this surfacing technology. However, there is still lack of knowledge regarding the applications and properties of powders fabricated especially for laser surfacing. One of these experiments is the subject of this contribution, where the laser weld deposits fabricated with powders composed of powder mixture based on NiCrSiB as a matrix with the CrB2 — TiB2 powder as the reinforcing phase were applied.
