Hard, Wear Resistant Metal Surfaces for Industrial Applications through Laser Powder Deposition

Abstract:

Most materials produced today are monolithic structures that are heat treated to perform a particular function. Laser Powder Deposition (LPD) is a technology capable of modifying a metallic structure by adding the appropriate material to perform a desired function (e.g., wear and corrosion resistance). LPD offers a unique fabrication technique that allows the use of soft (tough) materials as base structures. Through LPD a hard material can be applied to the base material with little thermal input (minimal dilution and heat-affected-zone {HAZ}), thus providing the function of a heat treatment or other surface modifications (e.g., carburizing, nitriding, thermal spray and electroplating). Several materials (e.g., Stellite 6 &21, 316 SS, 420 SS, M4, Rex 20, Rex 121, 10V, AeroMet 100, CCW+, IN 625 and IN 718) have been deposited on to carbon steel (4140, 4340, 1566, 1018) substrates to provide various functions for a number of industrial applications. These surface modifications have been evaluated through standard wear testing (ASTM G-65), surface hardness (Rc), micro-hardness (vickers), and optical microscopy. The results from these evaluations will be presented along with several industrial application case studies.

Overlap Ratio in Wire- and Powder-Based Laser Metal Deposition of H11 + Nb for Hot Forging Dies

Authors: Mahesh Teli, Fritz Klocke, Kristian Arntz, Kai Winands, Nils Klingbeil, Jon Iñaki Arrizubieta

Abstract: AISI H11 tool steel is a complex tool steel alloy used to manufacture hot forging dies. These dies however have a limited life, which depends upon the working conditions, the tool design, the heat treatment, and the quality of tool steels. In this paper, a novel wire-and powder-based laser metal deposition (WP-LMD) process was investigated to deposit H11 wire and niobium (Nb) powder simultaneously and develop a coating on existing forging dies for enhancing their life. The main aim was the development of a novel WP-LMD process, and consequently a new H11 tool steel with improved toughness and hardness. The developed WP-LMD process was later implemented to build a multilayer block made of the modified H11 tool steel. The overlap ratio was optimized in both, horizontal and vertical, directions, and were found to be 30% and 20% respectively in order to achieve a fully dense coating and avoid pores and unmelted Nb particles. The potential of the WP-LMD can be used to fabricate an outer layer of the modified H11 tool steel with improved toughness and hardness, which ultimately enhances the life of hot forging.

Effects of Rare Earth Y₂O₃ on the Microstructure and Wear Behaviors of Ti-6Al-4V Cladding with SiC

Authors: Yuan Ching Lin, Tzu Hsuan Wang

Abstract: This study elucidates the effect of the percentage of Y₂O₃ on the microstructure and tribological performance of Ti-6Al-4V clad by SiC and Ni powder, using gas tungsten-arc welding (GTAW). The microhardness of the clad layer was measured using a Vickers hardness tester. The microstructure of the clad layer was analyzed using a scanning electron microscope (SEM) and an electron probe micro-analyzer (EPMA). X-ray diffraction (XRD) was used to determine the constituent phases of the clad layer. A pin-on-disk rotating tribometer was used to evaluate the wear resistance of the substrate and the clad layer. According to the experimental results, TiC and TiSi₂ reinforcing phases were formed in situ in the clad layer during cladding process. The microhardness of the clad layer was two to three times that of the substrate, and the wear loss of the clad layer was about 51.5%~14.7% of that of the substrate. The optimal amount of Y₂O₃ enhanced the formation of TiC and TiSi₂ and thus improved the microhardness of the clad layer. However, an amount of Y₂O₃ that over a critical value reduced the formation of reinforcing phases and degraded the mechanical properties of the clad layer.
