摘要:
A novel solution route has been developed that after heat-treatment to 500-600° C. under inert atmosphere, yields highly porous composites of nano-sized metal (Ni) particle inclusions in ceramics (Al2O3). Metal loadings could be made from 95% Ni. The metal inclusion sizes in the Ni—Al2O3 system with the 10 atom % Ni sample were 4-7 nm, while for the 75 atom % Ni sample they were 5-8 nm. It was shown that the 10 atom % Ni sample could be used as a catalyst for the conversion of CO2 and CH4 in the temperature range 550-700° C., while higher temperatures led to growth of the Ni particles and carbon poisoning over time. The solution routes could also be deposited as thin dense films containing

摘要:
There is disclosed a method of coating cemented carbide inserts at least partly with a layer of at least one iron group metal. When inserts coated with such a layer are brazed to a tool holder, a joint with improved strength is obtained. According to the present method, one or more metal salts of at least one iron group metal containing organic groups are dissolved and complex bound in at least one polar solvent with at least one complex former comprising functional groups in the form of OH or NR.sub.3 (R.dbd.H or alkyl). A soluble carbon source is added to the solution which is subsequently at least partly applied to the cemented carbide inserts by dipping, spraying or painting. The inserts are dried and heat treated in an inert and/or reducing atmosphere. As a result, cemented carbide inserts are obtained at least partly coated with a layer of an iron group metal.
