Microstructure and Fatigue of EA4T Steel in Laser Cladding Remanufacturing

Laser remanufacturing based on the integration of reverse engineering and laser cladding

Laser remanufacturing has been used as an approach to refurbish or to improve the surface quality of high-priced parts. However, most of the existing systems lack measuring and modelling functions, which results in the uncertainty of the quality of end products. This paper presents a three-dimensional Laser Remanufacturing System (LRS) based on the integration of reverse engineering and laser c...

Microstructure Study of Laser Surface Cladding of Bearing Materials

Progress and Challenges of Ultrasonic Testing for Stress in Remanufacturing Laser Cladding Coating

Stress in laser cladding coating is an important factor affecting the safe operation of remanufacturing components. Ultrasonic testing has become a popular approach in the nondestructive evaluation of stress, because it has the advantages of safety, nondestructiveness, and online detection. This paper provides a review of ultrasonic testing for stress in remanufacturing laser cladding coating. ...

The effect of overlapping percent on microstructure and mechanical properties of laser cladding of Inconel 625 powder on ASTM A592 steel

In this study, the effect of overlapping percentage on microstructure and mechanical properties of a single-pass coating by Inconel 625 powder laser has been investigated for quench-tempered ASTM A592 steel. In order to have a structural analysis, the inter dendritic distance was evaluated. For this purpose, scanning electron microscopy (FESEM) and Digimizer software were adopted. In order to i...
