Definitions
- the invention relates to a finely divided, small particles of base metal dispersion dispersion strengthened platinum material.
- Out DE 39 02 342 C2 is a stabilized alloy of a comstabilizing constituent and, apart from impurities, gold and one or more platinum group metals as the remainder, the group of platinum metals being platinum, rhodium, palladium, ruthenium, iridium, the stabilizing constituent is an oxide, Carbide, nitride and / or silicide of scandium, yttrium, thorium, zirconium, hafnium, titanium, aluminum or a lanthanide, its content is not more than 0.5 wt .-% and the gold content in the range of 2 to 10 wt .-% lies.
- DE 100 46 456 describes a dispersion strengthened Au-free Pt material having either 0.01 to 0.5 wt% Sc or 0.05 to 0.5 wt% Sc mixed with Zr, Y or Ce.
- the object of the present invention is to save Pt without loss of quality.
- a dispersion-strengthened platinum material according to the invention consists of less than 99 wt.%, In particular between 95 and 99 wt .-% of a noble metal component of platinum or a platinum alloy consisting of at least 55 wt .-% Pt, 0 to 30 wt .-% Rh, 0 to 15 wt .-% Au and 0 to 40 wt .-% Pd, and the remaining over 1 wt .-%, in particular 1 to 5 wt .-% dispersion coagulant of at least 90 wt .-% oxygen-oxidized metals selected from
- the dispersion consolidator has at least 90% of oxidized Ce or Zr, in the case of Zr additionally Sc or Y. Based on the body volume, it is possible according to the invention to lose more than 10% by volume of noble metal, especially save Pt.
- the dispersion consolidator consists of at least 90% by weight of oxygen oxidized Ce, in particular when the platinum alloy has 0 to 30% by weight of Au.
- the dispersion consolidator consists of at least 90% by weight Zr oxidized with oxygen as the main component of the dispersion consolidator and Sc or Y as a minor component of the dispersion consolidator.
- Dispersion-strengthened platinum materials having from 1 to 4% by weight of Zr and from 0.05 to 1% by weight of Sc or Y, in which the sum of Sc and Y amounts to not more than 1% by weight, have proven useful.
- the mass ratio of Zr to the sum of Sc and Y is preferably 2: 1 to 50: 1, in particular 5: 1 to 20: 1.
- a solid body of a metal alloy is converted by at least 90% oxidation of the dispersion-strengthening metals into a dispersion-strengthened platinum material.
- Dispersion-reinforced platinum materials according to the invention are extremely resistant to wear and are suitable for use under abrasive conditions.
- Spark plug electrode tips, glass processing tools or parts thereof consisting of the dispersion-strengthened platinum material according to the invention are particularly durable.
- the ingot was planed to eliminate casting defects and forged at 1100 ° C into a 10 mm x 65 mm cross section plate. Subsequently, the plate was rolled at 1000 ° C to a 4 mm thick sheet. According to the patents DE 197 58 724 C2 and DE 100 46 456 C2 As indicated procedure, the sheet was aged for 14 days at 1000 ° C under air atmosphere. By hot gas extraction analysis (LECO method), the oxygen content was determined to be 4380 ppm. With complete oxidation of the Zr doping to ZrO 2 , the Sc doping to Sc 2 O 3 and the Y doping to Y 2 O 3 , the oxygen content would have reached 4430 ppm.
- LECO method hot gas extraction analysis
- the bar was rolled at 1000 ° C to a square wire (4 mm x 4 mm).
- the wire was paged for 10 days at 1000 ° C under air atmosphere.
- the oxygen content was determined to be 4500 ppm. With complete oxidation of the Zr doping to ZrO 2 , the Sc doping to Sc 2 O 3 and the Y doping to Y 2 O 3 , the oxygen content would have reached 4530 ppm.
- the structure of the annealed wire showed a uniform distribution of round and elongated oxide particles with dimensions between ⁇ 1 ⁇ m and 3 ⁇ m at intervals of approximately 1 up to 3 ⁇ m.
- An analogously prepared wire of an oxide dispersion hardened platinum material according to DE 100 46 456.4 with 1800 ppm Zr, 150 ppm Sc, 170 ppm Y and 770 ppm oxygen had a hardness of 155 and after annealing for one hour at 1000 ° C a hardness of 67.
- the density was increased by water displacement (according to Archimedes) with 20, 42 g / cm 3 , corresponding to a weight reduction of 4.8% for a given volume.
- the material is 1.7% by weight of base metal oxide, resulting in a total precious metal spam of 6.5% by weight per unit volume.
- Example 1 The sheet of Example 1 was annealed at 1000 ° C for 30 minutes under an air atmosphere, cold rolled to a thickness of 0.5 mm and annealed again at 1000 ° C for 30 minutes. From the sheet was by forming and welding according to the Wotfram inert gas method (see http://www.gieisbau-weit.de/site/schweissen/schweisshabilit. Htm) using conventional PtRh10 wire as welding filler a lining for a Ceramic stirrer made. The stirrer was used to perform melt tests on borosilicate glasses in an inductively heated PtRh10 crucible at 1550 ° C.
- the sheet was aged for 14 days at 1000 ° C under air atmosphere.
- the oxygen content was determined to be 2250 ppm.
- the oxygen content would have reached 2360 ppm.
- the sheet was rolled at 1050 ° C to a thickness of 2.5 mm and annealed at 1100 ° C for 2 hours under an air atmosphere. Subsequently, the sheet was cold rolled to a thickness of 0.8 mm.
