New plant for immersion post-treatment of mass plated work. Rinsing controlled by electrolytic conductivity; selective high-rate precious metal plating.Use of gold-based multilayer systems for electrical contact surfaces; alloys - new properties by structural modifications; electroless plating on zinc oxide sensitised glass; development of new zinc alloy plating systems with enhanced corrosion properties; oxide surfaces & oxide particles modified with polythiophenes; thermal stability of nanocrystalline nickel-18% tungsten alloys; electrochemical microcells & surface analysis; development of oxide-based PVD dry lubricants; discussion session on hexavalent chromium; GDOES for measurement of hydrogen profiles in plated components; GDOES to determine composition of chemically formed multilayers; characterisation of intermetallic phases of tin & copper using surface resistance; new XRF configuration for thickness meas't on very small items; Determination of cleanliness & residual surface soil on metals for thermal treatment; spot precision cleaning & in-situ cleanliness meas't of micro-components & interconnectors.
Oberflaechentage 2001. Part 2. 
Pt 2 of a lengthy report on German Surface Finishing event reports lectures on use of GDOES (glow discharge emission spectroscopy) as an analytical tool (e.g for hydrogen depth profiles in metals) & other depth profiles. Metallurgy & phase structure of tin-copper, incl. intermetallics. X-Ray fluoresence for thickness meas't & analysis of very small items. Cleanliness testing, mainly electrochemical & particle counting. Spot-cleaning to high standards, e.g in electronics prior to gold bonding, and instrumental methods of cleanliness testing, mostly spectroscopic. Process control in electroplating of microprocessors, incl. analysis using voltammetry & HPLC & ion chromatography. A 2-stage process for colourless, transparent conversion coating that is chromate-free. based on trivalent chromium. Protection of zinc surfaces with organic top-coat of acrylate & styrene as a form of conversion coating. Inclusion of 2nd phase allows such coatings to provide active corrosion protection. Troubleshooting metallised plastic components where stress cracking was found after temperature cycling test DIN53496. Stress in the plastic moulding seemed to be the cause. A highly automated machine which dried plated parts, carries through chromating and prepares them for organic coating, with 50% rinsewater & other savings. Case study of rinsing process after zinc plating, controlled by electrolytic conductivity meas'ts. Two discussion Forums, one on hexavalent chromium & chromates, one on environmental issues. A range of points was made.
