Abstract
The aim of the invention is to supply a sinterable powder mixture for producing sintered components, particularly in the automobile industry, by means of which components have both adequate mechanical strength properties and especially a high degree of hardness. Said aim is achieved by a powder mixture, 60 to 98.5 percent by weight of the total quantity of which consist of a basic Al powder made of metals and/or alloys thereof, comprising Al, 0.2 to 30 percent by weight of Mg, 0.2 to 40 percent by weight of Si, 0.2 to 15 percent by weight of Cu, 0.2 to 15 percent by weight of Zn, 0.2 to 15 percent by weight of Ti, 0.2 to 10 percent by weight of Sn, 0.2 to 5 percent by weight of Mn, 0.2 to 10 percent by weight of Ni, and/or less than 1 percent by weight of As, Sb, Co, Be, Pb, and/or B, the percentage by weight being in relation to the total quantity of the basic Al powder, and 0.8 to 40 percent by weight of a metal powder selected among a first group of metals and/or alloys thereof, consisting of Mo, W, Cr, V, Zr, and/or Y, the percentage being in relation to the total quantity of the powder mixture.
Description
The present invention relates to a kind of sintered component that is used to prepare, especially for the sinterable powder mixture based on the Al powder of the sintered component of vehicle structure, by the sintered component of this mixture preparation, and the method for preparing this base part.
Based on the property of aluminium, it is a kind of special preferred material in aerospace industry and automotive industry.With common for example being compared by the parts of cast iron preparation, it is very light to prepare parts by aluminium or alumina-bearing material.Because weight saving has for example just improved efficient in automobile, and reduce fuel consumption and improved the exhaust gas emission value.
Along with wishing that vehicle weight alleviates, just all the more to use aluminium at automotive field.Therefore for example in engine structure and drives structure, steel so far or foundry goods prepare being substituted or use aluminium by part ground by aluminium part.Because when making steel or foundry goods and aluminium part combined,, replace by the parts of using the aluminium manufacturing so wish " routine " parts of making by steel or foundry goods as much as possible because the different physical property of its material can go wrong.This has just been avoided the material therefor caused problems in aspect such as thermal expansivity, thermal conductivity, elasticity that do not coexist.Particularly also can reach higher efficient by using the mutual adaptive parts that are equipped with aluminum.
Because particularly a lot of engine parts, clutch components and drive unit are made by powder metallurgy, importantly to prepare powdered mixture and provide this mixture of a kind of usefulness to prepare the method for aluminium parts by powder metallurgy.Particularly aluminium and its alloy are easy to be covered with the metal oxide of stabilizer pole thereon when contacting with air to adopt the shortcoming of powder metallurgy preparation of parts of aluminium.Particularly increased specific surface thus.Because the oxide skin that exists on employed alumina-bearing material, this has just stoped particle necessary diffusion when sintering of the powdered material that is adopted.In addition, compare with the parts of being made by steel or foundry goods, the parts of being made by alumina-bearing material have the intensity level of reduction, particularly low hardness.In addition, containing the oxide skin mutual cold weld of meeting prevention particulate in common pressing process that exists on the aluminium starting material.
Therefore need sintered powdered mixture, it can carry out well processed through powder metallurgy, and can prepare the parts with good strength value and high rigidity through powder metallurgy thus.In addition, also need a kind of powder metallurgy process that is used to process the aluminiferous sinterable powder mixture of this class.
Therefore, the object of the present invention is to provide a kind of powdered mixture and by its parts made and corresponding method, they do not have above-mentioned shortcoming.
The objective of the invention is to be used to prepare sintered component by a kind of, be suitable for particularly that the sinterable powder mixture of the parts of vehicle structure reaches, this powdered mixture contains the 60-98.5 weight % by the powdered mixture total amount, the Al based powders that constitutes by metal and/or its alloy of preferred 75-92 weight %, this Al based powders contains Al and is respectively 0.2-30 weight %Mg by Al based powders total amount, 0.2-40 weight %Si, 0.2-15 weight %Cu, 0.2-15 weight %Zn, 0.2-15 weight %Ti, 0.2-10 weight %Sn, 0.2-5 weight %Mn, 0.2-10 weight %Ni and/or less than the As of 1 weight %, Sb, Co, Be, Pb and/or B, this powdered mixture also contains the 0.8-40 weight % by the powdered mixture total amount, and preferred 8-15 weight % is selected from by Mo, W, Cr, V, the first group of metal that Zr and/or Y form and/or the metal-powder of its alloy.
By adding first group of metal and/or its alloy of being made up of Mo, W, Cr, V, Zr and/or Y, available this powdered mixture has the very parts of high rigidity through the powder metallurgy preparation.Compare raising 5-35% with the parts of the powdered preparation that does not add this first group of metal and/or its alloy with the hardness value of the parts that are added with the powdered preparation that is selected from first group of metal and/or its alloy, preferred 10-25%.Improved especially by pressing process by in the Al based powders, adding first group of metal and/or its alloy, particularly the mutual cold weld of the closely knit caused particle in back.Finally also improved each particulate diffusion in each sintering process thus, so just made parts with higher-strength value and higher hardness.
In addition, also to contain second group of metal and/or its alloy be made up of Cu, Sn, Zn, Li and/or Mg be favourable to this sintered powdered mixture.The adding of described second group of metal and/or its alloy may cause with the Al based powders to form alloy and/or intermetallic phase during the back is closely knit during pressing process especially.Stop formation thus in the used lip-deep oxide skin of Al based powders.In addition, in the sintering process of reality, it is liquid that this second group of metal and/or its alloy are transformed into to small part down to small part in sintering temperature, has particularly improved first group of metal and/or the bonding of its alloy on aluminium base powder thus.
