Brass coatings on the cord are currently used to promote the bond but deterioration takes place with time and corrosion of the underlying steel occurs eventually. Zinc-cobalt coatings have been used as a replacement for brass. These coatings are capable of being drawn in the cord making operation provided that the cobalt content is 1.5wt%. Pull-out tests after vulcanising show that zinc-cobalt promotes similar adhesive strengths to that achieved with brass coatings. After ageing in warm moist conditions for up to 16 days the zinc-cobalt coating maintained higher levels of adhesion than brass. In tyre tests the zinc-cobalt coatings were superior in preventing red rust formation on the steel","PeriodicalId":23268,"journal":{"name":"Transactions of The Institute of Metal Finishing","volume":"77 1","pages":"71-74"},"PeriodicalIF":1.9,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/00202967.1999.11871250","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58742416","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}

The preparation of conductive particles (5 ∼ 7 μm diameter ) by electroless nickel plating has now been investigated. Generally, batch type electroless plating is applied to provide conductivity on nonconductors. Since the surface areas of particle s are much larger than the bulk substrate, accordingly the electroless plating bath becomes unstable. The continuous dropping method has therefore been applied, in the preparation of conductive particles Uniform coverage of deposited nickel on the particles was obtained by using ammonium acetate as a complexing agent, and surface coverage was further improved without coagulation of particles by treatment with a surface active agent before their introduction to the plating bath.","PeriodicalId":23268,"journal":{"name":"Transactions of The Institute of Metal Finishing","volume":"77 1","pages":"41-43"},"PeriodicalIF":1.9,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/00202967.1999.11871242","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58742056","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}

The resultant deposits were then characterised using SEM, TEM and XRD. Microhardness surveys were carried out on the coatings together with abrasive wear tests. Coatings 250 μm thick, were produced with low oxides and porosity levels. The most consistent coatings were prepared from powder sources with a minimum particle size of 25 μm. Coating microstructures were either nano-crystalline or mixtures of amorphous and microcrystalline phases Boron additions to the powder encouraged the formation of amorphous coatings and higher microhardness values i.e. > 675 Hv. The formation of boride precipitates in the coatings does not appear to raise their hardness as the precipitates were either of larger diameter > 500 nm or present in low volume fractions Limited amounts of oxides were produced in the coatings, e.g. as α-Cr 2 O 3 or spinel oxide NiCr 2 O 4 particularly at intersplat boundaries. Abrasive wear resistance of the PSI-1 coating was superior to the other two coatings because it contains more amorphous material. The combination of wear and corrosion resistance associated with these coatings may prove to be attractive in many applications where both these properties are needed, carbides and borides.","PeriodicalId":23268,"journal":{"name":"Transactions of The Institute of Metal Finishing","volume":"77 1","pages":"60-63"},"PeriodicalIF":1.9,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/00202967.1999.11871248","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58742397","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}
