材料的活性屏等离子渗氮

近年来,等离子渗氮技术的迅速发展和在表面工程领域的应用呈现出减缓的趋势,其原因是传统的直流等离子体技术存在一些固有的缺点,例如,炉温难以保持均匀,等离子体不够稳定以及因打弧而引起工件表面损伤等。克服这些不足之处的努力促使了活性屏等离子渗氮(ASPN)技术的发展。本文从技术和环境优势角度证明,ASPN可以应用于低合金钢、工具钢、不锈钢以及能进行传统直流等离子渗氮的其他钢种。此外,ASPN可以处理不适合直流等离子渗氮的非导电材料,如经氧化处理的钢和高分子材料。从长远看,对环境友好且技术先进的等离子渗氮比传统的盐浴和气体渗氮更有优势。活性屏等离子渗氮技术是充分发挥等离子体技术在化学热处理及有关表面工程中应用潜力的新方法。

Surface characterisation of plasma treated flexible substrates for waveguide-on-flex application

This paper reports the physical and chemical effects of argon, nitrogen and oxygen plasma treatments on the surface properties of flexible circuit materials. Both KaptonHN™ and Vecstar™ films selected as optical flexible substrates under plasma irradiation were studied by atomic force microscope (AFM), contact angles, X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS). The etch rate enhancement of the polymeric materials is more pronounced in oxygen plasma than in argon or nitrogen plasma. The increases of surface functional groups (-COOH, -CNOH) of plasma-modified polymer films are correlated with the increased presence of polar component in surface free energy. While the plasma treatment on KaptonHN™ substrates have been widely discussed in literature, the detailed characterisation of both pristine and different plasma surface modified Vecstar™ films is reported and compared for the first time.

Active screen plasma nitriding of materials

Abstract

The rapid development and the uptake of plasma nitriding technology into industrial surface engineering have slowed down in recent years. This is attributed to some of the inherent shortcomings of conventional dc plasma technology, for example, difficulties in maintaining a uniform chamber temperature, instability of the plasma and potential surface damage to parts caused by arcing. Efforts in overcoming these problems have led to the development of active screen plasma nitriding (ASPN) technology. This review demonstrates that with all its technological and environmental advantages, ASPN can be used to treat low alloy steels, tool steels, stainless steels and other steels which can conventionally be nitrided with dc plasma technology. In addition, ASPN can be used to treat non-conducting materials such as oxidised steels and polymeric materials which are not suitable for a dc plasma nitriding system. In the longer term, environmental friendly and technologically advanced plasma nitriding will outperform conventional salt bath and gaseous methods. Active screen plasma nitriding is a novel way of possibly achieving the full potential of plasma technology for thermochemical surface engineering.

New developments on the use of polymeric materials in sheet metal forming

Advanced polymers offer at the present time concrete possibilities in reducing the product development time and production of prototypes and small series of sheet metal parts. However, the applicability of such materials requires different approaches in comparison to conventional materials for sheet metal forming dies. This paper presents investigation results dealing with tribological and tool design aspects for the use of polymeric materials in sheet metal forming. Friction and wear of sheets with different surface topologies have been investigated. A new test method for measuring polymer/sheet wear is presented. A coupled simulation model for the production of a test geometry aimed specifically at the investigation of die deformations and loads is presented. The behaviour of two polymeric materials by forming the test geometry has been simulated and the maximal loads and deformations during the process have been quantified. Simulation results have been subsequently validated in experimental testing.     

Effect of atmospheric microwave plasma treatment on organic lubricant on a metallic surface

Coaxial injection microwave excited plasma torch, operating at atmospheric pressure has been tested to treat greased metallic surfaces. The treatment conditions were controlled using optical emission spectroscopy. The plasma treatment was carried out using argon plasma, with argon or oxygen in the periphery. The effect of plasma treatment on the grease was evaluated, using gravimetric analysis by weighing the sample before and after treatment, surface energy and X-ray photoelectron spectroscopic measurements. Initial period of treatment yielded etching of the grease, but, later on, the grease stabilized forming polymeric films, independent of the gas present in the periphery. The etching behavior was explained by different mechanisms involved in the plasma grease surface and sub-surface interactions.
