Impact Of Solidification On Tensile Strength Of Cocr 2lc In Selective Laser Melting, Stefan Robert Popp
Selective laser melting (SLM) is an additive manufacturing technique with which parts of nearly arbitrary shape and complexity can be produced. The parts are generated layer for layer directly out of a 3D CAD model completely without forming tools.
In this work, the selective laser technique is applied to a CoCrMo alloy. Due to its high corrosion resistance, wear-resistance, and heat resistance, this alloy is mainly used for medical or high temperature applications.
A systematic approach is used to investigate the influence of the process parameters laser power and exposure time (pulsed laser) on density, melt pool dimensions, melt pool ...
A Decision Support Methodology For Improving Equipment Reliability, Caiqiao Xu
Purpose - Aggressive Maintenance Strategy can improve the overall operation and reliability through redesigning or modifying equipment. A decision support tool is proposed that could aid in discovering the many options and in selecting the best approach for redesigning or for modifying the equipment. The new tool has three sections that correspond to the equipment life cycle:
1. Keeping the equipment in perfect running condition.
2. Identifying defects as soon as the equipment starts to degrade.
3. Minimizing losses after the equipment has ceased functioning.
Design/Methodology – The first section seeks to keep the equipment running in perfect condition. There are ...
