Increased Tool Performance with Rockit LAserGenerated Surfaces
Purpose and goal
The project is a collaboration between Luleå University of Technology (LTU) and three world leading companies; Höganäs, Sandvik SMRT and SPH. The project aims at verifying excellent wear and impact properties for the newly developed cobalt free cladding powder called Rockit during laser cladding. The understanding of the process and consequentially resulting material properties will increase. Furthermore, drill heads for rock drilling and soil tips will be laser cladded with Rockit and thereafter be tested in real environments.
Expected results and effects
It is attractive for customers to use tools that lasts longer. Fewer changes of drill heads during deep drilling can provide large profits since a drill head change may require several hours. For farmers it is critical to be able to work when the weather allows, which improved cultivation tips enable. For both Sandvik SMRT and SPH, this means that means that market shares can be retained or even increase. Optimised and investigated process behaviour and resulting wear properties for Höganäs new cobalt free powder may give rise to new applications and thereby open new market segments.
Planned approach and implementation
The project is divided into three stages: 1. LTU will with Höganäs new powder Rockit optimise laser cladding for relevant provided substrates, regarding process efficiency and resulting microstructure. 2. The creation of specimens and characterisation of these surfaces will be performed primarily by LTU, but also complemented by Höganäs. 3. Laser cladding of demonstrators from SPH and Sandvik will be performed and also tested in real environment for further evaluation. In this stage, an implementation plan is also developed and the results are disseminated in suitable channels.
