Definitions
- ABSTRACT A cobalt/chromium based alloy suitable for use in [30] Foreign Application Priority Data making dental prostheses and surgical implants, and May 26, 1972 Germany 2225577 for in making machine Parts which are subject to severe corrosive conditions and mechanical loads at 52] us.
- c1 75/171, 3/1, 32/2, high temperatures, comprises by Weight 26 Percent to 32/10 A 31 percent chromium, from 4 percent to 6.5 percent 51 1m.
- Cobalt/chromium alloys are used in machinery construction predominantly for making components which are subjected to severe corrosive conditions and me chanical loadings at high temperatures. They are however equally well known in surgery for the making of implants and in dentistry for making prosthetic struc tures.
- alloys which, in addition to cobalt as the basic element, also contain by weight from 26 percent to 31 percent chromium, from 4 percent to 6.5 percent molybdenum, up to 1 percent each of silicon, manganese and iron, and from 0.3 percent to 0.5 percent carbon, are of particular importance.
- alloys are also used which, principally owing to the cost of cobalt content, contain instead up to 20 percent nickel. These may also have the silicon and manganese contents raised up to 6 percent, and may also be provided with additions of copper, aluminium, titanium, niobium, vanadium, zirconium, tantalum, beryllium and boron, either individually or in combination.
- a disadvantage of these cobalt/chromium alloys is their low capacity for deformation, that is low ductility. This is usually expressed by the elongation at rupture. The published values vary considerably but are predominantly in a range from 2 percent to 6 percent. The highest value published is 8 percent. Because of these low elongation values for the alloys, severe limits are set on the plastic deformations which can be applied to articles made from them, for example straightening operations on the holding braces of dental prosthetic structures, if the risk of breakage is to be avoided.
- titanium-containing alloys with a cobalt base having improved capacity for deformation for the same or an increased strength have been developed. These alloys contain, by weight, in addition to cobalt, from percent to percent chromium, from 5 percent to percent nickel, up to 3 percent molybdenum, up to 1 percent carbon, silicon, manganese, aluminium and/or iron and from 4 percent to 10 percent titanium.
- alloys having a cobalt/chromium base which, in addition to cobalt, contain, by
- an alloy comprises, by weight, from 26 percent to 31 percent chromium, from 4 percent to 6.5 percent molybdenum, up to 2 percent, and preferably only up to 1.5 percent silicon, up to 6 percent and preferably only up to 3 percent manganese, up to 1 percent iron, up to 0.5 percent boron, up to 0.5 percent carbon and from 0.15 percent to 0.5 percent nitrogen the remainder cobalt except for impurities, and the sum of the carbon and nitrogen contents not exceeding 0.7 percent
- the nitrogen content is preferably from 0.20 percent to 0.35 percent, or advantageously up to a maximum of only 0.30 percent.
- both the silicon and the manganese contents should not exceed 1 percent each.
- Example 4 to 6 and 9 the manganese content has been raised to approximately 3 percent, in order to increase the dissolving capacity of the alloys for nitrogen.
- An addition of boron improves the capacity for casting (Examples 5 and 6).
- the mechanical properties are not in any way thereby adversely affected.
- An alloy consisting essentially of from 26 percent to 3l percent chromium, from 4 percent to 6.5 percent molybdenum, up'to 2 percent silicon, up to 6 percent manganese, up to 1 percent iron, up to 0.5 percent boron, up to 0.5 percent carbon, from 0. [5 percent to 0.5 percent nitrogen, with the ,balance being cobalt and impurities, the sum of said carbon content and said nitrogen content not exceeding 0.7 percent.
- a dental prosthesis made from an alloy as claimed in claim 1.
- a surgical implant made from an alloy as claimed in claim 1.
