Bremseorganet fremstilles ved at en aluminiumbasert smelte bringes til å stivne under trykk i en smeltepressform og at den aluminiumbaserte legering utstyres med et slitasjebestandig skikt. Dette skikt består av en krom-karbon-jern-legering som inneholder 10-30 %, fortrinnsvis 15-20 % krom og fortrinssvis 2-4 % karbon.

The layer has a thickness of 0.3-1.0 mm and is preferably applied by plasma spraying.
Description
Oppfinnelsen vedrører en fremgangsmåte for fremstillingThe invention relates to a method for production
av en ny type bremseelementer for friksjonsbremser, hvor bremseflaten eller sliteflaten utgjøres av et belegg på et aluminiumbasert organ som bærer bremseflaten eller sliteflaten, mot hvilket organ det kan presses et bremsebelegg. Spesielt vedrører oppfinnelsen bremseflater i skivebremser og trommel-bremser. of a new type of brake elements for friction brakes, where the braking surface or the wearing surface consists of a coating on an aluminum-based body that carries the braking surface or the wearing surface, against which body a brake lining can be pressed. In particular, the invention relates to braking surfaces in disc brakes and drum brakes.
Oppfinnelsen skal beskrives under henvisning til skivebremser på biler, men vedrører generelt en fremgangsmåte for fremstilling av et forbedret element med friksjonsflate mot hvilken et bremsebelegg kan presses. Bremseskiver er for tiden vanligvis fremstilt av støpejern, seigjern eller stål. Dette innebærer at det foreligger en relativt stor masse som roterer uavfjæret, en relativ stor tendens til korrosjon, og relativ lav motstandsevne mot slitasje, noe som forkorter leve-tiden og medfører øket slitasje av bremsebelegget. Videre er jernlegeringenes varmeledningsevne forholdsvis lav, noe som fører til temperaturdifferanser og vanskeligheter med å an- The invention shall be described with reference to disc brakes on cars, but generally relates to a method for producing an improved element with a friction surface against which a brake lining can be pressed. Brake discs are currently usually made of cast iron, ductile iron or steel. This means that there is a relatively large mass that rotates unsprung, a relatively large tendency to corrosion, and a relatively low resistance to wear, which shortens the service life and leads to increased wear of the brake lining. Furthermore, the iron alloys' thermal conductivity is relatively low, which leads to temperature differences and difficulties in applying
ordne en effektiv kjøling. Ved skivebremser for biler kan temperaturen ved gjentatte og kraftige bremsinger øke til 700°C og høyere i friksjonsskiktet, noe som igjen fører til vanskeligheter med høye bremsevæsketemperaturer og kjøling. arrange efficient cooling. In the case of car disc brakes, the temperature during repeated and heavy braking can rise to 700°C and higher in the friction layer, which in turn leads to difficulties with high brake fluid temperatures and cooling.
Man har således i lang tid forsøkt å løse de ovennevnte problemer. Således er det i den svenske patentsøknad 7809374-7 beskrevet_en bremseflate bestående av et termisk pålagt kermet-skikt på en aluminiumbasert metallkomponent. I kermetskiktet utgjøres den keramiske komponent av metalloksyder av f.eks. metallene aluminium, titan, zirkonium eller krom. Beleggene av kermet gir imidlertid store problemer med hensyn til binding til aluminiumbasisen og frem til nå har man ikke funnet noen bremseskiver av denne type på markedet. Ifølge et eldre tysk patent nr. 825032 foreslås en bremse- eller koblingsskive av lettmetall som kan utstyres med et flateskikt av stål. Heller ikke denne konstruksjon er så vidt vites markedsført. I tilleggspatent til nevnte tyske patent, patent nr. 843634, er det også nevnt at flateskiktet kan bestå av kromstål, vanadium-stål, manganstål eller lignende. Attempts have therefore been made for a long time to solve the above-mentioned problems. Thus, in the Swedish patent application 7809374-7, a braking surface consisting of a thermally applied cermet layer on an aluminum-based metal component is described. In the ceramic layer, the ceramic component consists of metal oxides of e.g. the metals aluminium, titanium, zirconium or chrome. The coatings of the frame, however, cause major problems with regard to bonding to the aluminum base and until now no brake discs of this type have been found on the market. According to an older German patent no. 825032, a brake or clutch disc made of light metal is proposed which can be equipped with a surface layer of steel. Nor, as far as is known, has this construction been marketed. In the supplementary patent to the aforementioned German patent, patent no. 843634, it is also mentioned that the surface layer can consist of chrome steel, vanadium steel, manganese steel or the like.
Oppfinnelsen vedrører således fremstillingen av et bremseorgan av den type som inngår i bremsesysterner, hvor bremsebelegg presses mot et bremseorgan av en aluminiumbasert legering og hvor bremseorganet er utstyrt med et slitasjebestandig skikt og oppfinnelsen er kjennetegnet ved at en aluminiumbasert smelte bringes til å stivne under trykk i en smeltepressform og at bremseorganet utstyres med et slitasjebestandig skikt, bestående av en krom-karbon-jern-legering som inneholder 10-30%, fortrinnsvis 15-20% krom og 2-4% karbon. The invention thus relates to the production of a brake element of the type included in brake systems, where brake linings are pressed against a brake element of an aluminum-based alloy and where the brake element is equipped with a wear-resistant layer and the invention is characterized by the fact that an aluminum-based melt is brought to solidify under pressure in a melt press mold and that the brake member is equipped with a wear-resistant layer, consisting of a chrome-carbon-iron alloy containing 10-30%, preferably 15-20% chromium and 2-4% carbon.
Ved anvendelsen av bremseorgan i form av skiver presses vanlig bremsebelegg mot det slitasjebestandige skikt som er anbragt på aluminium. Energien som derved omvandles til varme, ledes av aluminiumet til kaldere områder. På grunn av aluminium-ets gode varmeledningsevne transporteres varmen relativt hurtig til alle aluminiumbasisens deler. I tilfelle med en bremse-skive kan denne spyles av kjølende luft eller være utstyrt med kanaler for kjølende medium. Skiven kan også utgjøre en inte-grert del av det hjul som den vanligvis er tilsluttet til. Således kan hele felgen være støpt i et stykke og tjene som kjøle-element. Felgen kan eventuelt også utstyres med ekstra kjøle-flenser og lignende og derved tilveiebringe en optimal kjøling av bremseskiven. When using brake means in the form of discs, normal brake lining is pressed against the wear-resistant layer which is placed on aluminium. The energy that is thereby converted into heat is led by the aluminum to colder areas. Due to aluminum's good thermal conductivity, the heat is transported relatively quickly to all parts of the aluminum base. In the case of a brake disc, this can be flushed with cooling air or be equipped with channels for cooling medium. The disc can also form an integrated part of the wheel to which it is usually connected. Thus, the entire rim can be cast in one piece and serve as a cooling element. The rim can optionally also be equipped with additional cooling flanges and the like and thereby provide optimal cooling of the brake disc.
Den aluminiumlegering som benyttes bør hensiktsmessig ha et høyt smelteintervall og ikke på grunn av legeringstilsetninger ha en i sammenligning med rent aluminium dårlig varmeledningsevne. En god varmeledningsevne må kombineres med god evne til å tåle varme. Det ligger helt innenfor fagmannens kunnskap å velge en egnet legerina med disse ønskede egenskaper. Egnede legeringer er AA 2618, AA 2014 og AA 5056, som ved smiing eller smelte-pressing (såkalt squeeze forming eller squeeze casting) kan oppnå ønskede kombinasjoner av egenskaper. The aluminum alloy that is used should appropriately have a high melting interval and not, due to alloy additions, have a poor thermal conductivity compared to pure aluminium. A good thermal conductivity must be combined with a good ability to withstand heat. It is entirely within the expert's knowledge to choose a suitable alloy with these desired properties. Suitable alloys are AA 2618, AA 2014 and AA 5056, which can achieve desired combinations of properties by forging or melt-pressing (so-called squeeze forming or squeeze casting).
Det slitasjebestandige skikt påføres bremseorganet ved hjelp av en egnet metode. En foretrukket metode er plasma-sprøyting som muliggjør at man direkte påsprøyter skiktmetallet på basismetallet, idet det oppnås en god vedhefting mellom basismetallet og metallet i skiktet. Ved plasmasprøyting på-virkes også vedhef tingen av partiklcelstørrelsen. til det ved plasmasprøytning benyttede legeringspulveret. En partikkel-størrelse på 20-200 ym har vist seg å være hensiktsmessig og gir en overordentlig god vedhefting uten anvendelse av spesielle bindeskikt mellom basismetall og slitasjeskikt. Som antydet ovenfor kan andre metoder for pålegging av et skikt av legeringsmetall på basismetallet anvendes, men for oppnåelsen av god vedhefting må derved ofte skikt med god vedhefting til så vel basismetall som legeringsmetall i skiktet anvendes som bindeskikt. Det er også mulig å påføre det slitasjebestandige skikt ved finfordeling av belegningsmetall, påføring av de smeltede finfordelte dråpene til det smeltepressede aluminiumsbaserte basismetall og tetning av det påførte skikt ved hjelp av kulepressing. En annen foretrukket metode innbefatter at smeltepressformens indre på hver sin side utstyres med et 0,3-1,0 mm tykt skikt av slitasjebestandig krom-karbon-jern-legering og smeltepressingen skjer i nærvær av disse to skikt hvorved begge disse gjenfinnes på støpestykket. Denne metode innebærer at etterarbeidet i stor grad kan unngås. Det er også mulig å oppnå en meget god binding mellom den aluminiumsbaserte legering og det slitasjebestandige skikt ved smeltepressingen. Denne binding kan ytterligere forbedres ved at skiktet med slitasjebestandig krom-karbon-jern-legering utstyres med spor eller andre overflatefestende formgivingsdetaljer på den blivende grenseflate mellom basismetall, og slitasjebestandig metall. Det ligger innenfor fagmannens kunnskap å velge egnede metoder for påføring av skiktet og behovet for anvendelsen av bindeskikt. En ytterligere metode er f.eks. inn-støping av sliteskiktet. The wear-resistant layer is applied to the brake element using a suitable method. A preferred method is plasma spraying, which makes it possible to directly spray the layer metal onto the base metal, as a good adhesion is achieved between the base metal and the metal in the layer. In plasma spraying, adhesion is also affected by the particle size. to the alloy powder used in plasma spraying. A particle size of 20-200 ym has proven to be appropriate and provides extremely good adhesion without the use of special bonding layers between base metal and wear layer. As indicated above, other methods for applying a layer of alloy metal to the base metal can be used, but in order to achieve good adhesion, layers with good adhesion to both base metal and alloy metal in the layer must therefore often be used as a bonding layer. It is also possible to apply the wear-resistant layer by finely distributing the coating metal, applying the molten finely divided droplets to the melt-pressed aluminum-based base metal and sealing the applied layer by means of ball pressing. Another preferred method involves equipping the interior of the melt press mold on each side with a 0.3-1.0 mm thick layer of wear-resistant chrome-carbon-iron alloy and the melt pressing takes place in the presence of these two layers whereby both of these are found on the casting. This method means that post-work can be largely avoided. It is also possible to achieve a very good bond between the aluminum-based alloy and the wear-resistant layer during the melt pressing. This bond can be further improved by providing the layer of wear-resistant chrome-carbon-iron alloy with grooves or other surface-fixing shaping details on the remaining interface between base metal and wear-resistant metal. It is within the expert's knowledge to choose suitable methods for applying the layer and the need for the use of a bonding layer. A further method is e.g. embedding of the wear layer.
Ved anvendelsen av plasmasprøyting benyttes et sprøyte-pulver med en slik sammensetning at det oppnådde slitasjeskikt har en sammensetning bestående av 10-30 % krom og 2-4 % karbon og resten jern og vilkårlige forurensninger. Således må det tas hensyn til at en viss mengde karbon og krom går tapt ved forbrenning ved plasmasprøytingen. Krom som er oppløst i jernet erønskelig da bremseorganets korrosjonsbestandighet økes. Slitasjebestandigheten beror på dannelsen av kromkar-bider og forholdet krom-karbon er således av betydning. Den benyttede legering har således vesentlig høyere karboninnhold enn vanlig kromstål. When using plasma spraying, a spray powder is used with such a composition that the wear layer obtained has a composition consisting of 10-30% chromium and 2-4% carbon and the rest iron and arbitrary impurities. Thus, it must be taken into account that a certain amount of carbon and chromium is lost during combustion during the plasma spraying. Chromium that is dissolved in the iron is desirable as the corrosion resistance of the brake element is increased. The wear resistance depends on the formation of chromium carbides and the chromium-carbon ratio is thus important. The alloy used thus has a significantly higher carbon content than ordinary chrome steel.
Det slitasjebestandige skikt bør ha en tykkelse på 0,3-1,0, fortrinnsvis 0,3-0,5 mm for oppnåelsen av et til-fredsstillende resultat. Den øvre .grense er ikke kritisk og innebærer en optimalisering med hensyn til de økende påførings-kostnader ved øket tykkelse. Den nedre grense representerer en tykkelse som tillater anvendelsen av bremseorganet i en vesentlig tid uten reduksjon av slitasjebestandigheten og muliggjør kommersiell anvendelse på biler med en, med vanlige bremser sammenlignbar levetid. The wear-resistant layer should have a thickness of 0.3-1.0, preferably 0.3-0.5 mm to achieve a satisfactory result. The upper limit is not critical and involves an optimization with regard to the increasing application costs with increased thickness. The lower limit represents a thickness that allows the use of the braking device for a significant time without reducing the wear resistance and enables commercial use on cars with a lifetime comparable to conventional brakes.
Det er også vesentlig at det påførte skikt ikke er altfor porøst, idet porøse skikt har lavere varmeledningsevne, dårligere korrosjonsegenskaper og dårligere slitasjebestandig-het. It is also essential that the applied layer is not overly porous, as porous layers have lower thermal conductivity, poorer corrosion properties and poorer wear resistance.
