Several other sample preparation methods were developed to simplify the solution-deposition procedures. For example, Cooks and coworkers studied adduct ion formation (cationization) of several organic compounds when the organic was burnished (rubbed) onto a metal foil, mixed with a metal salt and then burnished onto a metal foil, or just mixed with metal powders or salts and pressed into pellets. Not only did the SIMS spectra show dramatic differences is the efficiency of adduct ion formation for different metals, but the sample preparation methods had an equally dramatic effect on the SIMS spectra [18]. 

He used spectrochemical techniques to study the composition of burnished molybdenum disulphide films from preparation to eventual failure. He found that the film surface at failure contained little molybdenum disulphide but contained molybdic oxide, sulphur, sulphate and iron compounds. In the presence of antimony trioxide, however, there was preferential oxidation of the antimony trioxide to the tetroxide Sb204. On heating a mixture of molybdenum disulphide and antimony trioxide in air at 500 C and 600 C, he found by X-ray diffraction that the products were mixtures of molybdenum disulphide and antimony tetroxide. Neither molybdic oxide M0O3 nor antimony trioxide was present. When molybdenum disulphide alone was heated under the same conditions, it was almost completely converted to molybdic oxide. 

The applicability of the analysis for a plastically deformed solid film on an elastically deformed substrate is not restricted to films of soft metals. This effect applies also to burnished films of other kinds of solid substances which can act as lubricants. Some of the practical ways of utilizing solids as lubricants involve compounding them with a substance, often an organic plastic of low shear strength, which bonds them to the surface to be protected, and hence the mechanical properties... 

It is applied to the ware as a suspension of gold powder in essential oils, with or without the addition of a proportion of BRIGHT GOLD (q.v.) Other ingredients are a flux (e.g. lead borosilicate or a bismuth compound) to promote adhesion to the ware, and an extender such as a mercury salt. This type of gold decoration is dull as taken from the kiln, hence the need for subsequent burnishing, cf. acid... 

The addition of Purple of Cassius gold, tin oxide, tin compounds, iron oxide, or aluminum oxide to burnish gold compositions was shown to increase the firing tonpaature up to 1400°C, and also increased the mechanical and chemical durability of the resultant gold film [85]. Best results were obtained on firing in combination with an intermediate layer consisting of one or a mixture of high...
