In the aqueous suspensions of powders mineral

摘要

P the invention relates to a novel process for the quenching of metal parts intended to reduce the stresses due to the tempering without affecting the characteristics of sensitive. This method consists in immersing the parts, by immersion in a suspension in water of a binder of the clay and of a mineral filler such as magnetite, ferro-silicon, baryta. / p & & p & the addition of products, corrosion inhibitors, defoamers or antiflocculating may be made to this suspension. The present invention applies to the metal parts, but more particularly to the aluminium alloys having high resistance as their shape or dimension is subject to defects caused by the toughening stresses that are excessive. / p
