Description

Wynalazek niniejszy dotyczy stopu, przeznaczonego glównie do wyrobu lo¬ zysk.Istota wynalazku polega na drobnym dodatku molibdenu lub zwiazków, albo sto¬ pów molibdenowych do mieszaniny z olo¬ wiu antymonowego, cyny, miedzi i niklu.Bardzo odpowiedni jest stop skladaja¬ cy sie z 8 — 25% cyny, 0,5 — 2,0% molibdenu, 0,5 — 2,0% niklu, 0,5 — 2,0% miedzi, 13 — 20% antymonu i cyny, a w czesci pozostalej — z olowiu.Stop ten okazal sie w praktyce tanim i nadzwyczaj pewnym.Zastosowanie molibdenu pozwala prze- dewszystkiem na uzycie w charakterze ma- terjalu zasadniczego taniego olowiu anty¬ monowego. Dzieki ponadto molibdenowi, a zwlaszcza w zwiazku z niklem uzyskuje sie doskonale polaczenie wszystkich me¬ tali stqpu, a w nastepstwie zarówno roz¬ ciagliwosc jak i sprezystosc tegoz.W porównaniu ze znanemi obecnie me¬ talami lozyskowemi dodatek molibdenu wprowadza to znaczne polepszenie stopu, ze sporzadzone zen lozyska zyskuja na trwalosci i zdolnosci pracy przy najwiek¬ szych nawet obciazeniach.Nowy stop staje sie wskutek dodatku molibdenu latwo plynnym, dzieki czemu mieszanina dokladnie wypelnia forme.Podobniez i na metale .lozyskowe, tak zwane twarde, a mianowicie bronzy, skla¬ dajace sie z Cu, Sn i Ni dodatek molib¬ denu wplywa nader dodatnio, nadajac lo¬ zyskom, wykonanym z tych metali,znaczniejsza odpornosc na scieranie, tu¬ dziez wieksza trwalosc. Bronzy te moga posiadac sklad najrozmaitszy. PL PLThe present invention relates to an alloy primarily intended for the manufacture of profit. The essence of the invention consists in the fine addition of molybdenum or molybdenum compounds or alloys to a mixture of antimony lead, tin, copper and nickel. An alloy consisting of from 8 - 25% tin, 0.5 - 2.0% molybdenum, 0.5 - 2.0% nickel, 0.5 - 2.0% copper, 13 - 20% antimony and tin, and in the remainder - from Lead. This alloy has proved to be cheap and extremely reliable in practice. The use of molybdenum allows, above all, the use of cheap antimony lead as a basic material. Moreover, thanks to molybdenum, and especially in connection with nickel, a perfect combination of all alloy metals is obtained, and consequently both their tensile strength and elasticity. Compared to the presently known bearing metals, and the addition of molybdenum, this significantly improves the alloy that The bearings gain durability and the ability to work even with the highest loads. The new alloy becomes easily liquid due to the addition of molybdenum, thanks to which the mixture fills the mold exactly. Similarly, also for bearing metals, the so-called hard, namely bronzes, With Cu, Sn and Ni, the addition of molybdenum has a very positive effect, giving the bearings made of these metals a greater resistance to abrasion, and also greater durability. These bronzes can be of a variety of compositions. PL PL
