A range of different substrate types (grit blasted, ground, milled and cold rolled) have been electroless nickel plated to three different thicknesses and tested for porosity. The nature of the type of pretreatment and its effect on deposit porosity has also been investigated. Talysurf measurements have shown that the surface morphology does not change significantly with deposit thicknesses up to 24 μm.Data obtained from microscopy, profilometric, electrochemical and corrosion rate measurements are used to illustrate the importance of these factors in controlling the degree of porosity in the EN deposit and the rate of corrosion o...","PeriodicalId":23268,"journal":{"name":"Transactions of The Institute of Metal Finishing","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"1998-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/00202967.1998.11871215","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58741324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Much effort has been devoted since the signing of the Montreal Protocol to finding replacement cleaning agents for these and other banned or controlled substances and it is now clear that a variety of different cleaning processes must be developed. In the long term it is likely that the vast majority of industrial cleaning will be carried out in aqueous solutions making it necessary to investigate the special problems involved in cleaning difficult components. A review, which summarises the issues and current problems being encountered in the search for replacement cleaning processes, is presented. Also considered are the relevant techniques and experimental procedures which can be used to investigate surface cleanliness and related phenomena.","PeriodicalId":23268,"journal":{"name":"Transactions of The Institute of Metal Finishing","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"1998-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/00202967.1998.11871200","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58741151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Disadvantages of Nb are its high material costs and the fact that it is not possible to deposit Nb by the rather economic technique of aqueous electrodeposition. However, other deposition techniques such as physical vapour deposition may be used to produce niobium coatings. Due to its high melting point, sputtering is the preferred PV D deposition technology.Improved corrosion resistance approaching that of bulk Nb was found for lμm thick Nb coatings on 304 stainless steel substrates The corrosion performance very much depends on the method of ion etching prior to deposition.

Zn-Fe alloys with compositions ranging from less than 5 wt-% to more than 75 wt-% Fe have been electrodeposited from a single electrolyte, making this system ideal for production of compositional modulated alloy (CMA) electrodeposits. Chloride content, pH and agitation of the electrolyte have been observed to have a strong influence on the reaction at the cathode surface, just as the use of pulse reversal current during electrodeposition.
