Description
Oppfinnelsen angår legeringer for anvendelse som lager-materialer og av den generelle type som er kjent som "hvittmetall" som kan beskrives som legeringer hvori en hovedsakelig komponent utgjøres av tinn, bly eller kadmium. The invention relates to alloys for use as bearing materials and of the general type known as "white metal" which can be described as alloys in which a main component is tin, lead or cadmium.
Det tas ved oppfinnelsen sikte på å tilveiebringe en slik legering som på en effektiv måte kan bindes til et underlags-materiale av stål eller et annet materiale og som har en god strekkfasthet og duktilitet, slagfasthet og utmatningsfasthet. The invention aims to provide such an alloy which can be effectively bonded to a base material of steel or another material and which has good tensile strength and ductility, impact strength and fatigue strength.
Oppfinnelsen angår således en legering som er særpreget ved at den består av 0-1,5 vekti kadmium, fra spormengder til 9 vekt% kobber, fra spormengder til 13 vekt% antimon, 0-2 vekt% mangan, The invention thus relates to an alloy which is characterized by the fact that it consists of 0-1.5% by weight of cadmium, from trace amounts to 9% by weight of copper, from trace amounts to 13% by weight of antimony, 0-2% by weight of manganese,
0-2 vekt% nikkel, 0,001-0,5 vekt% krom, 0,005-0,5 vekt% kobolt og resten tinn. 0-2 wt% nickel, 0.001-0.5 wt% chromium, 0.005-0.5 wt% cobalt and the rest tin.
Det fremgår at legeringen ikke inneholder beryllium, men'kobolt som en vesentlig komponent sammen med krom. It appears that the alloy does not contain beryllium, but cobalt as an essential component together with chromium.
Det har vist seg at hvittmetall som inneholder krom kan It has been shown that white metal containing chromium can
få en sterkt forbedret mikrostruktur og egenskaper som lagermateriale ved innarbeidelse av kobolt, og denne forbedring kan oppnås selv når legeringen størkner langsomt fra smeltet tilstand, som vanlig er ved fremstilling av lågere med et massivt stålunder-lag, og det er derfor en stor fordel ved legeringen at selv ved langsom størkning kan tilfredsstillende lagermaterialeegenskaper erholdes. get a greatly improved microstructure and properties as a bearing material by incorporating cobalt, and this improvement can be achieved even when the alloy solidifies slowly from the molten state, which is common in the production of bearings with a massive steel substrate, and it is therefore a great advantage of the alloy that even with slow solidification satisfactory bearing material properties can be obtained.
Ett resultat av langsom avkjøling er at lengden av de derved dannede nålekrystaller av kobber/tinn i en legering som inneholder kobber, er tilbøyelig til å øke sterkt dersom avkjølingen har vært langsom, men dersom kobolt er tilstede, som i legeringen ifølge oppfinnelsen, har det ved forsøk under kontrollerte laboratoriebeting-elser vist seg atøkningen i nålekrystallengden ikke er vesentlig større når avkjølingen One result of slow cooling is that the length of the resulting needle crystals of copper/tin in an alloy containing copper tends to increase greatly if the cooling has been slow, but if cobalt is present, as in the alloy according to the invention, it has in tests under controlled laboratory conditions, the increase in the needle crystal length has been shown to be not significantly greater when the cooling
er langsom. is slow.
En foretrukken mengde kobolt er 0,3 vekt% for å oppnå denne innvirkning på nålelengden. A preferred amount of cobalt is 0.3% by weight to achieve this effect on needle length.
En tilsetning av bare 0,05 vekt% kobolt til hvittmetall-legeringen kan imidlertid øke strekkfastheten av den kokillestøpte legering med ca. 5% uten at dette innvirker på duktiliteten som holder seg i det vesentlige konstant på over 20%. Ved langsom av-kjøling kan legeringens strekkfasthet økes med ca. 20% sammenlignet med strekkfastheten for en legering som ikke inneholder kobolt. Efter langsom avkjøling kan strekkfastheten økes med ca. 20%. However, an addition of only 0.05% by weight of cobalt to the white metal alloy can increase the tensile strength of the die-cast alloy by approx. 5% without this affecting the ductility, which remains essentially constant at over 20%. With slow cooling, the tensile strength of the alloy can be increased by approx. 20% compared to the tensile strength of an alloy that does not contain cobalt. After slow cooling, the tensile strength can be increased by approx. 20%.
I den nedenstående tabell er gjengitt strekkfastheten, den prosentuelle forlengelse og hardheten for 8 legeringer fremstilt med langsom avkjøling og som ikke inneholder kobolt sammen med kr6m, og for en niende legering ifølge o<p>pfinnelsen, og forbedringen av lageregenskapene fremgår av tabellen. The table below shows the tensile strength, the percentage elongation and the hardness for 8 alloys produced with slow cooling and which do not contain cobalt together with Cr6m, and for a ninth alloy according to the invention, and the improvement in the bearing properties is shown in the table.
Forbedringen av strekkfastheten som kan erholdes medøkende forholdsvise mengder av kobolt for en gitt legering fremgår av fig. 1, og det fremgår at efter tilsetning av ca. 0,1 eller 0,15% kobolt fås ikke noen vesentlig ytterligere forbedring av strekkfastheten. The improvement in tensile strength that can be obtained with increasing relative amounts of cobalt for a given alloy is shown in fig. 1, and it appears that after the addition of approx. 0.1 or 0.15% cobalt no significant further improvement in tensile strength is obtained.
På fig. 2 er vist hvorledes nålelengden for kobber/tinn In fig. 2 shows how the needle length for copper/tin
(Cu6, Cu3) avtar med økende koboltmengder og at noen vesentlig ytterligere reduksjon ikke fås efter at 0,2% kobolt er blitt til-satt. Den spesielle legeringssammensetning i hvert tilfelle var 3,46-3,72% kobber, 8,32-8,64% antimon, 0,79-0,91% kadmium og 0,094-0,10% krom med varierende mengder kobolt, idet resten ut-gjordes av tinn. (Cu6, Cu3) decreases with increasing amounts of cobalt and that no significant further reduction is obtained after 0.2% cobalt has been added. The particular alloy composition in each case was 3.46-3.72% copper, 8.32-8.64% antimony, 0.79-0.91% cadmium and 0.094-0.10% chromium with varying amounts of cobalt, being the rest was made of tin.
Den generelle virkning er den samme uansett krommengden innen området 0,005-0,5%. The general effect is the same regardless of the amount of chromium within the range of 0.005-0.5%.
Det kan generelt hevdes at de beste mekaniske egenskaper fås med ca. 0,1% kobolt, mens den fineste mikrostruktur fås med ca. 0,3% kobolt. It can generally be claimed that the best mechanical properties are obtained with approx. 0.1% cobalt, while the finest microstructure is obtained with approx. 0.3% cobalt.
En ytterligere fordel som erholdes ved bruk av krom og kobolt sammen er at legeringens mikrostruktur blir langt mindre ømfintlig overfor innvirkninger som skyldes tilstedeværelsen av arsen som er tilbøyelig til å gjøre kobber/tinn-utfellingen grovere når bare A further advantage obtained by using chromium and cobalt together is that the microstructure of the alloy becomes far less susceptible to effects due to the presence of arsenic which tends to coarsen the copper/tin precipitate when only
krom (eller krom og beryllium) er tilstede. chromium (or chromium and beryllium) is present.
