Definitions
- the drawbacks just referred to are removed by the present invention, which relates to a burnishing salt mixture and a burnishing proc- GSS'glIlIWhiCh the burnishing procedure is carried out "in a plurality of stages.
- the parts are treated for 50-60 minutes in two or three successive burnishing baths of diiferent '25 composition, and thereby acquire a covering layer of extraordinarily high resistance to mechanical wear and very good stability towards corrosion.
- a mixture consisting of 50 70% sodium hydroxide (NaOH), preferably NaOH, and
- a mixture consisting of 55-70%, preferably 10 60%, of sodium hydroxide (NaOH), 8-12%, pref erably 10%, of di-sodium phosphate (Na2HPO4+ 121-120) 10-18%, preferably 14%, of trisodium phosphate 5 and 2.5-4%, preferably 3%, of sodium nitrite (NaNOz)
- NaNOz sodium nitrite
- 'For preparing the burnishing bath 60 parts by weight of this salt mix- 20 ture are mixed with 40 parts by weight of water. The iron parts are heated in this bath, at 145-160, preferably at 150, with advantage for about 30 minutes.
- a process for burnishing steel and iron articles comprising immersing the parts first in a bath containing 73 to 77% sodium hydroxide, 14 to 22% disodium phosphate and 3 to 7% so- 35 dium nitrite, then in a bath containing '50 to sodium hydroxide, and 30 to 50% sodium nitrite and finally in a bath containing 55 to 70% sodium hydroxide, 8 to 12% disodium phosphate, 10 to 18% trisodium phosphate and 2.5 to 40 4% sodium nitrite.
- a process for burnishing steel and iron articles comprising immersing the parts first in a bath containing sodium hydroxide, 16.5% disodium phosphate and 5% sodium nitrite, then in a bath containing 60% sodium hydroxide, and 40% sodium nitrite and finally in a bath containing 60% sodium hydroxide, 10% disodium phos phate, 14% trisodium phosphate and 3% sodium nitrite. 60
