Towards additively manufacturing excavating tools for future robotic space exploration
Multiple metal alloys, additively manufactured through laser powder bed fusion, were tested as potential excavating tools for future robotic spacecraft landing on icy planetary bodies. Mechanical specific energy as a function of blade hardness was measured for each excavating tool as it trenched through soft and hard salt, where the salt is a regolith ...

Effects of Graphite Additions on Microstructures and Wear Resistance of Fe-Cr-C-Nb Hardfacing Alloys
Hardfacing alloys with varying amounts of graphite content were prepared on a surface of 45 steel using flux-cored wire open-arc overlaying. Testing was conducted using SEM, TEM, XRD, a Rockwell hardness apparatus and an abrasion tester to study the ...

Investigating the Possibility of Regenearation by Hardfacing for Forging Tools Based on Analysis of Tool Working Conditions and Wear Evaluationy [PDF]
Tests were performed on example tools applied in hot die forging processes. After withdrawal from service due to excessive wear, these tools can be regenerated for re-use through machining and hardfacing. First, analysis of worn tools was carried out for
