Description

454 890 10 15 20 25 30 35 2 Även genom DE-A 25 25 185 är slitfasta formdetaljer kända, som består av en hårdmetallbaskropp och två över varandra liggande delskikt, varav det yttre utgöres av ett extremt slitstarkt delskikt av aluminiumoxid och/eller zir- konoxid, medan det inre delskiktet består av en eller flera borider, speciellt diborider av elementen titan, zirkon, hafnium, vanadium, niob, tantal, krom, molybden och volfram. 454 890 10 15 20 25 30 35 2 Also through DE-A 25 25 185 are wear-resistant mold details known, which consists of a cemented carbide base body and two over superimposed sublayers, the outer of which consists of a extremely durable sublayer of alumina and / or zirconium conoxide, while the inner sublayer consists of one or more borides, especially diborides of the elements titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum and tungsten.

Vid dessa kända formdelar har det inre och det yttre del- skiktet vartdera en tjocklek mellan 0,5 och 20/um.In these known molded parts, the inner and outer parts have the layer each has a thickness between 0.5 and 20 .mu.m.

Slutligen är genom GB-PS 1 509 752 stål- eller hård- metallverktyg kända, som är försedda med flera, olika sam- mansatta hârdmaterialskikt, varvid beläggningens tjocklek ligger mellan 1 och 50/um och de enskilda skiktens tjock- lek mellan 0,5 och 20/um.Finally, GB-PS 1 509 752 steel or hard metal tools known, which are provided with several, different manned hard material layers, the thickness of the coating is between 1 and 50 .mu.m and the thickness of the individual layers play between 0.5 and 20 / um.

Kända sammansatta kroppar medför olägenheten att hård- materialbeläggningarna vid nötande belastning ännu icke vi- sar tillräcklig vidhäftning. Speciellt i oxidskikten bil- das lätt sprickor, som leder till att beläggningarna flag- nar av.Known composite bodies cause the inconvenience of hardening the material coatings at abrasive loads have not yet sufficient adhesion. Especially in the oxide layers easily crack, which causes the coatings to flake nar av.

Uppfinningen har därför fått till uppgift att åstad- komma en sammansatt kropp, vars bindmetallfria hårdmate- rialskikt förutom hög avnötningshâllfasthet uppvisar för- bättrad vidhäftning, eftersom de hårda skiktens goda slit- egenskaper endast kan nå full effekt om hårdmaterialskik- ten även är tillräckligt fast förbundna med baskroppen resp med varandra. Dessutom skall hårdmaterialbeläggningen 'ha hög brottseghet och således kunna tåla högre seghetsbe- lastningar.The invention has therefore been given the task of a composite body whose binder metal-free hard material material layers in addition to high abrasion resistance exhibit improved adhesion, as the good wear of the hard layers properties can only reach full effect if the hard material are also sufficiently firmly connected to the base body respectively with each other. In addition, the hard material coating should have high fracture toughness and thus be able to withstand higher toughness loads.

Den till grund för uppfinningen liggande uppgiften löses i enlighet med de i patentkravets 1 kännetecknande del angivna särdragen därigenom att hårdmaterialskiktet med en tjocklek mellan 3 och 15/um är anordnat direkt på baskroppen och uppbyggt av ett mycket stort antal tunna enkelskikt med en tjocklek av vartdera 0,02 - 0,1/um, vilka omväxlande består av titankarbid eller titannitrid eller titankarbonitrid å ena sidan och aluminiumoxid eller zir- konoxid eller zirkonkarbonitrid å andra sidan, varvid så- J* ef' V 10 15 20 25 30 35 454 890 3 ledes hârdmaterialsammansättningen i varje enkelskikt skil- jer sig från de båda intilliggande enkelskiktens hàrdmate- rialsammansättning.The object underlying the invention dissolved in accordance with the features of claim 1 part specified features by that the hard material layer with a thickness between 3 and 15 .mu.m is arranged directly on the base body and made up of a very large number of barrels single layers with a thickness of each 0.02 - 0.1 .mu.m, which alternately consists of titanium carbide or titanium nitride or titanium carbonitride on the one hand and alumina or conoxide or zirconium carbonide on the other hand, J * ef ' V 10 15 20 25 30 35 454 890 3 the hard material composition in each single layer is from the hard materials of the two adjacent single layers. rial composition.

Man har funnit att på överraskande sätt en enligt upp- finningen utförd sammansatt kropp förutom genom hög slit- hállfasthet utmärker sig genom påtagligt förbättrad vidhäft- ning av hela hårdmaterialbeläggningen, trots att hårdmate- rialbeläggningen kan vara uppbyggd av såväl tjockare hård- materialskikt som av ett mycket stort antal tunna hârdmate- rialenkelskikt. vid nötande belastning av den sammansatta kroppen i det av Det får anses såsom synnerligen oväntat att många tunna enkelskikt bestående hârdmaterialskiktet energi- slukande förlopp äger rum, som mycket kraftigt begränsar sprickbildning i hårdmaterialskikten och förhindrar att hârdmaterialbeläggningen flagnar av i förtid. Den samman- satta kroppen enligt uppfinningen uppvisar dessutom hög brottseghet och kan således motstå högre seghetspâkänningar.It has been found that, surprisingly, a the composite body except in the case of high wear durability is marked by markedly improved adhesion of the entire hard material coating, despite the fact that the hard the material coating can be made up of both thicker material layers which of a very large number of thin hard materials rialenkel layer. at abrasive load of the composite body in it of It may be considered extremely unexpected that many thin single layers consisting of the hard material layer energy- devouring process takes place, which very severely limits cracking in the hard material layers and prevents the hard material coating peels off prematurely. The combined The body according to the invention also has a high fracture toughness and can thus withstand higher toughness stresses.

Enligt uppfinningen vidareutvecklas den sammansatta kroppen genom att närmast baskroppen av hârdmetall applice- ras ett titankarbidskikt, på vilket befinner sig resten av hårdmaterialskiktet av många tunna enkelskikt av omväxlande titannitrid och aluminiumoxid. Vidare kan på det samman- satta hårdmaterialskiktet_sitta ett yttre hårdmaterialskikt av aluminiumoxid.According to the invention, the compound is further developed the body by applying closest to the base body of cemented carbide a titanium carbide layer, on which the rest of the hard material layer of many thin single layers of alternating titanium nitride and alumina. Furthermore, on the put the hard material layer_sit an outer hard material layer of alumina.

På grund av sina goda förslitningsegenskaper användes den sammansatta kroppen enligt uppfinningen såsom slitdel samt för bearbetning av metalliska och icke metalliska mate- rial.Due to its good wear properties it was used the composite body according to the invention as a wear part and for processing metallic and non-metallic materials rial.

Den sammansatta kroppen kan tillverkas enligt kända beläggningsförfaranden, varvid CVD-förfarandet visat sig särskilt lämpligt. De många tunna enkelskikten kan identi- fieras genom elektronmikroskopiska förfaranden.The composite body can be manufactured according to known coating procedures, whereby the CVD procedure proved particularly appropriate. The many thin single layers can be identified performed by electron microscopic procedures.

Därefter appliceras i samma ugn på titankarbidskik- tet vid en temperatur på 1000°C och 50 millibar tryck under 250 minuter ett 3/um tjockt hârdmaterialskikt, som omväx- lande består av 19 titannitrid- och 19 aluminiumoxidskikt.A cemented carbide base body having the shape of a reversible cut, provided in an oven with a temperature of 1000 ° C and a press 50 millibar for 100 minutes with a 3 / um thick hard material layer of titanium carbide, the titanium carbide through 454 890 10 15 20 25 30 4 a gas phase reaction is formed by titanium tetrachloride, methane and hydrogen. Then apply in the same oven on the titanium carbide layer. at a temperature of 1000 ° C and 50 millibar pressure below 250 minutes a 3 .mu.m thick layer of hard material, which grows consists of 19 titanium nitride and 19 alumina layers.
