The Micro-Geometry Evaluation on Steel Sheets after Chemical Surface Treatment

Chemical Surface Treatment of Stainless Steel

Mechanical Property Determination of Heavy Steel Plates and Cold Rolled Steel Sheets by Micro-magnetic Ndt

The presentation is to results recently obtained in collaborative research in the European steel programme performed by Fraunhofer-IZFP and co-operative steel industry producing rolling products. The objective was and is to characterize i.e. to predict mechanical properties like hardness, yield strength, tensile strength, deep drawing parameters rm and ∆r, etc., mainly online by use of contact-...

Neural Network-Based Evaluation Method for Surface Glossiness of Steel Sheets

Assurance of surface glossiness is one of the most important factors in the production of stainless steel strips, but the surface glossiness has been evaluated by off-line measurement and visual inspection. For the purpose of on-line evaluation of the surface glossiness, an optical measurement method of the surface glossiness and a neural network-based discriminant method have been developed. F...

Geometry and surface - assisted micro flow discretization ∗

This paper presents a micro flow discretization system that autonomously digitizes continuous liquid flow into nanoliter segments. Powered by the interactions between liquid flow and micro-channels, the discretization process does not consume any electricity or require any external control. In the prototype demonstration, the discretizer is made of PDMS microfluidic channels with desired geomet...

The Effect of Surface Treatment on Corrosion behavior of Surgical 316L Stainless Steel Implant

The AISI 316 L Stainless Steel (SS) specimens were exposed to passivation surface through two different processes including; holding in 40-vol% HNO3 at temperature of 60 ºC for 30 min and 15-vol%H2SO4 at ambient temperature for 1 hour. The corrosion behavior of specimens was evaluated in physiological solutions by electrochemical in vitro tests through linear an...
