Smoother and stronger high speed sintered elastomers through surface modification process

Experimental Study on the Surface Modification by Electrical Discharge Process

The creation of modified layer on metal surfaces using new methods is one of the procedures in surface engineering which can improve the surface mechanical properties. The electrical discharge process is a new method that can form a modified layer on the metal surfaces. This study aims to improve of pure aluminum surface properties through Electrical Discharge process with Monel 400 electrode. ...

3D-Surface-Model for Injection Speed Process

Injection velocity control in plastic injection molding is challenging as this process is inherently nonlinear, requiring an adaptive control strategy for good tracking of complex velocity trajectories. In this paper, a surface based model approach is developed tracking complex trajectories of injection velocity. This technique employs a 3-dimensional (3D) nonlinear surface model of the control...

Coercivity enhancement of Nd-Fe-B sintered magnets by grain boundary modification via reduction-diffusion process

The interface between the Nd2Fe14B particles and the grain boundary surrounding them in Nd-Fe-B sintered magnets was modified by diffusion Dy metal selectively through the grain boundary involving the reduction of Dy2O3 or DyF3 with CaH2 and the coercivity of them was effectively enhanced from 0.98 MA/m to 1.42 MA/m with keeping the high value of remanence. The resultant coercivity was higher t...

Reduction of Surface hr~ >ion Caused by Helium Blistering in Sintered Beryllium and Sintered Aluminum Powder

Studies have been conducted to find Materials with microstructures which Minimize the formation of blisters. A promising class of materials appears to be sintered metal powder with small average grain sizes and low atomic number Z. Studies of the surface erosion of sintered aluminum powder (SAP 895) and of aluminum held at AOO'C due to blistering by 100 keV helium ions have been conducted and t...
