Definitions
- the fluo-silicate employed is preferably that of sodium which is the cheapest and most readily available, although I do not limit myself thereto, a very convenient, satisfactory and effective concentration in practical use is that wherein the bath contains 0.15% of this material, but I do not limit myself to this strength.
- a very convenient, satisfactory and effective concentration in practical use is that wherein the bath contains 0.15% of this material, but I do not limit myself to this strength.
- iron-group, metal I intend to designate nickel and cobalt and any convenient salt thereof can apparently be used. I have had excellent success with the sulphate, nitrate, and chloride of these metals. A very convenient and practical concentration of the same is from 0.2% to 0.3%, although I do not limit myself thereto.
- alkali salt I designate salts both of the fixed alkalies and of the volatile alkali, and the particular salt which I prefer to use is the nitrate although I have had a measurable degree of success with such other salts as the phosphate and sulphate.
- ammonium, sodium, or potassium nitrate I have found that 1% is a very satisfactory concentration although I do not limit myself thereto. It appears to be necessary that this third ingredient be preponderant.
- the solution is preferably employed hot, even up to the boiling point, and the articles to be treated are immersed therein for a greater or less length of time as determined by the extent of treatment desired which can readily be judged by the eye.
- the effect of this treatment is to produce upon the surface a mottled, speckled, or spotted appearance, irregular portionsof varying sizes and shapesbein covered with a dense adherent,
- the resulting coating is unaffected by heat and is highly resistant to abrasion even that of a steel brush, the unmodifiedaluminum surface yielding rather than the modified 'or coated portion.
- the surface can be very thoroughly covered with the coating described. Care however, must be observed not to permit too great proximity between metallic articles receiving simultaneous treatment.
- Stencils or other protective means can be employed if desired to shield any desired portion against the action of the solution.
- the solution can be used repeatedly although additions of the several ingredients are required from time to time. Eventually the solution becomes sufiiciently contaminated with impurities, partly dissolved from the articles and partly of accidental entrance so that it must be discarded.
- the articles after receiving the treatment hereinbefore described can be subjected, if desired, to further treatments designed to color the unmodified portions, or may be' covered with paint, lacquer, etc, which adheres much more strongly thereto than to the unmodified metal. Alloys of aluminum with other metals.
- a dipping I solution for aluminum articles comprising a soluble flue-silicate, a soluble salt of a nonferrous metal of the iron group, and an alkali nitrate, all dissolved in water.
