Active screen plasma nitriding enhances cell attachment to polymer surfaces
Active Screen Plasma Nitriding (ASPN) is a well-established technique used for the surface modification of materials, the result of which is often a product with enhanced functional performance. Here we report the modification of the chemical and mechanical properties of ultra-high molecular weight poly(ethylene) (UHMWPE) using 80:20 (v/v) N2/H2 ASPN, followed by growth of 3T3 fibroblasts on th...
متن کاملOsteoblastlike cell adhesion on titanium surfaces modified by plasma nitriding.
PURPOSE The aim of this study was to evaluate the characteristics of various titanium surfaces modified by cold plasma nitriding in terms of adhesion and proliferation of rat osteoblastlike cells. MATERIALS AND METHODS Samples of grade 2 titanium were subjected to three different surface modification processes: polishing, nitriding by plasma direct current, and nitriding by cathodic cage disc...
متن کاملthe effects of nitriding parameters in hot working steel aisi h13 on its surface properties and nitride layers during conventional and active screen plasma nitriding treatments
the main aim of this research was to investigate the effects of plasma nitriding parameters including frequency and duty cycle for a seris of test samples with different grooves during conventional plasma nitriding (cpn) and active screen plasma nitriding (aspn) treatments. the sample assemblies were consisted of rectangular grooved steel blocks with different groove dimensions of 2, 4, 6, 8 an...
متن کاملSurface Modification of Titanium by Plasma Nitriding
A systematic investigation was undertaken on commercially pure titanium submitted to plasma nitriding. Thirteen different sets of operational parameters (nitriding time, sample temperature and plasma atmosphere) were used. Surface analyses were performed using X-ray diffraction, nuclear reaction and scanning electron microscopy. Wear tests were done with stainless steel Gracey scaler, sonic app...
متن کاملLow Temperature Plasma Nitriding of Inner Surfaces in Stainless Steel Mini-/Micro-Pipes and Nozzles
Metallic miniature products have been highlighted as mini-/micro-structural components working as a precise mechanism, in dispensing systems, and in medical operations. In particular, the essential mechanical parts such as pipes and nozzles have strength and hardness sufficient for ejecting viscous liquids, solders, and particles. A low-temperature plasma nitriding process was proposed as a sur...
