Description

A Trójsystem: cyna — olów — antymon zbadany zostal na podstawie doswiadczen w granicach zawartosci1 cyny: 0—3%, dalej 6—15%, wkoncu zgóra 55% i wyniki sa przedstawione graficznie w dolaczonym wy¬ kresie. Na zalaczonym rysunku linja Sb— Sn, oznacza zawartosc antymonu, linja Sb— Pb oznacza zawartosc olowiu, linja Pb—Sn oznacza zawartosc cyny. Pola /, // i /// oznaczaja blizej okreslone rozpiecia pro¬ centowe w zawartosci skladowych czesci stopu odnosnie mozliwosci uszlachetniaja¬ cych, jak równiez wydobycia pozadanych wlasnosci i nadania cech wartosciowych stopom panewkowym. Stopy, które podlug poszczególnych pól moglyby przez specjal¬ ne domieszki zastapic metale panewkowe, bylyby: w polu / stopy o 0—3% cyny, 13 — 30% antymonu, reszta olów, z za¬ wartoscia miedzi lub bez, przyczem czesc olowiu moglaby byc zastapiona specjalnie dobranemi ciezkiiemi metalami, wzglednie metaloidami. W polu // stopy 6—15% cy¬ ny, 13 — 30% antymonu, reszta olów z zawartoscia miedzi lub bez, przyczem czesc olowiu bylaby zastapiona przez szczególnie dobrane ciezkie metale, wzglednie metaloidy dla otrzymania wla¬ snosci stopów panewkowych.W polu /// tegoz dolaczonego szkico¬ wego wykresu: cyny — olowiu, antymonu znajduja sie stopy z przeszlo 55% cyny, 8—20% antymonu z zawartoscia miedzi lub bez, reszta olów, przyczem czesc olo¬ wiu, dla osiagniecia wysokocennych wla¬ snosci panewkowych metali, zastepuje siespecjalnemi ciezkiemi metalami, wzglednie metaloidami. Ciezkiemi metalami, które po^ ciagaja za soba podniesienie sie specyficz¬ nych Hvlasaosci iych stopów, sa przewaz¬ nie: kadm, rtec, bizmut, jak równiez man¬ gan, nikiel, kobalt, zelazo, chrom, molib¬ den, wolfram, tal, Z tych szczególniej kadm, w» polaczeniu z manganem i niklem, wybitnie wyróznia sie przez wydatne pod¬ niesienie dodatnich wlasnosci tego rodzaju stopów olowianych. Z metaloidów: fosfor, arsen i t. d., szczególniej arsen w obecno¬ sci malych ilosci fosforu nadaje sie, by te¬ go rodzaju stopy olowiane, odpowiadaja¬ ce pomieszczonym w polach I i II gatun¬ kowo tak poprawic, izby one mogly zasta¬ pic pelnowartosciowy materjal cynowych stopów panewkowych, dzieki swym wla¬ snosciom mechanicznym i latwej przysto- sowalnosci praktycznej. Tego rodzaju sto¬ py z wysokim procentem olowiu, których zawartosc antymonu jest nadeutektyczna, wykazuja, przez dodanie specjalnie wybra¬ nych ciezkich metali, jednolita strukture/W jednolitej plastycznej masie znajduja siie równomiernie rozmieszczone twarde kry¬ sztaly mieszane warunkujace wlasnosci stopu panewkowego. Domieszki na skutek swego równomiernego roztworu w stopie i nastepnie zdolnosci szybkiego krzepniecia sprawiaja, ze twarde krysztaly mieszane spoczywaja równomiernie rozlozone1 jak¬ by w kratownicy wewnatrz plastycznej masy. Dzieki tym ciezkim metalom i do¬ mieszkom metaloidów, wzrastaja na tyle zalety mechaniczne stopu, np. twardosc, wytrzymalosc na cisnienie i zgniatanie i t d., ze dorównywuje on w zupelnosci ko¬ sztownym stopom panewkowym z wysoka zawartoscia cyny. Na skutek wlasnosci te¬ go rodzaju, stopy olowiane zastepuja w zupelnosci wysokoprocentowe stopy cy¬ nowe. PL PLA trisystem: tin - lead - antimony was tested on the basis of experiments within the limits of tin content: 0-3%, then 6-15%, finally top 55% and the results are presented graphically in the accompanying diagram. In the attached figure, the line Sb — Sn means the antimony content, the Sb— Pb line means the lead content, the Pb — Sn line means the tin content. The fields /, // and /// denote more precisely defined percentage spreads in the content of the alloy components with regard to the enhancement possibilities, as well as the extraction of the desired properties and giving value to acetabular alloys. The alloys that could replace the acetabular metals by special admixtures would be: in the field / alloys with 0-3% tin, 13-30% antimony, the rest of the lead, with or without copper, would be partially lead be replaced with specially selected heavy metals or metalloids. In the field, 6-15% of tin, 13-30% of antimony, the rest of the lead with or without copper, some of the lead would be replaced by specially selected heavy metals or metalloids to obtain the properties of bushing alloys. /// of the attached sketch diagram: tin-lead, antimony, there are alloys with more than 55% of tin, 8-20% of antimony with or without copper, the rest of the lead, with part of the lead, to achieve high-value properties acetabular metals, is replaced by special heavy metals or metalloids. Heavy metals, which attract the increase of the specific qualities of their alloys, are mainly: cadmium, mercury, bismuth, as well as manganese, nickel, cobalt, iron, chromium, molybdenum, tungsten, thallium. Of these, in particular, cadmium, in combination with manganese and nickel, is outstandingly distinguished by the significant increase in the positive properties of this kind of lead alloys. Of the metalloids: phosphorus, arsenic, etc., especially arsenic in the presence of small amounts of phosphorus, it is suitable to improve the quality of this type of lead alloys, corresponding to those located in fields I and II, in such a way that they could be full value material of tin acetabular alloys, thanks to its mechanical properties and easy practical adaptability. Such alloys with a high percentage of lead, the antimony content of which is hypereutectic, exhibit a uniform structure by the addition of specially selected heavy metals. In a uniform plastic mass there are uniformly distributed hard mixed crystals which determine the properties of the acetabular alloy. The admixtures, due to their homogeneous solution in the melt and then the ability to rapidly solidify, cause the hard mixed crystals to rest evenly distributed, as if in a lattice, inside the plastic mass. Due to these heavy metals and metalloid dopes, the mechanical advantages of the alloy, such as the hardness, pressure and crush strength, and hence completely equal to the high tin content, of the sided socket alloys, increase so much. Due to these properties, lead alloys completely replace the high-percentage tin alloys. PL PL
