Claims (14)

1. Sliddel med høj slidbestandighed og -styrke, omfattende: et legeme bestående af cementerede karbidpartikler, som er støbt med en stållegering med lavt kulstofindhold, hvor stållegeringen med lavt kulstofindhold har et kulstofindhold, som svarer til et kulstof svarende til Ceq=wt%C+0,3(wt%Si+wt%P) af 0,1 til 1,5 vægtprocent, hvor mindst én oxideringbeskyttelsescoating er anbragt i de cementerede karbidpartikler.
2. Sliddel ifølge krav 1, kendetegnet ved, at de cementerede karbidpartikler af legemet indkapsles af stålet med lavt kulstofindhold under støbning for at danne en matrix.
3. Sliddel ifølge krav 1 eller 2, kendetegnet ved, at volumenet af de cementerede karbidpartikler er 0,3 til 20 cm3.
4. Sliddel ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at den mindst én oxideringsbeskyttelsescoating er aluminiumoxid.
5. Sliddel ifølge krav 4, kendetegnet ved, at tykkelsen af aluminiumscoatingen er 1 til 8 pm.
6. Sliddel ifølge et hvilket som helst af de foregående krav, yderligere omfattende en flerhed af lag af oxideringsbeskyttelsescoating på de cementerede karbidpartikler.
7. Sliddel ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at de cementerede karbidpartikler har et binderfaseindhold af Ni.
8. Sliddel ifølge et hvilket som helst af krav 4 til krav 7, yderligere omfattende et for-lag af TiN, der er coatet på de cementerede karbidpartikler under alu- miniumscoatingen.
9. Sliddel ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at de cementerede karbidpartikler blotlægges ved en overflade af sliddelen.
10. Sliddel ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at de cementerede karbidpartikler har en tykkelse på 5 til 15 mm.
11. Fremgangsmåde til fremstilling af en sliddel med høj slidbestandighed og høj styrke, som omfatter de følgende trin: tilvejebringe en mængde cementerede karbidpartikler; coate de cementerede karbidpartikler med mindst ét lag af oxideringsreducerende materiale; placere de cementerede karbidpartikler i en form; levere smeltet stållegering med lavt kulstofindhold i formen, hvor indholdet af stållegeringen med lavt kulstofindhold svarer til et kulstof svarende til Ceq=wt%C+0,3(wt%Si+wt%P) af 0,1 til 1,5 vægtprocent, og indkapsle de coatede cementerede karbidpartikler med den smeltede stållegering med lavt kulstofindhold for at støbe en matrix af cementerede karbidpartikler og stållegering med lavt kulstofindhold.
12. Fremgangsmåde ifølge krav 11, kendetegnet ved, at trinnet med coating af de cementerede karbidpartikler omfatter påføring af et lag af aluminiumoxid.
13. Fremgangsmåde ifølge et hvilket som helst af kravene 11-12, kendetegnet ved, at trinnet med coating omfatter påføring af en aluminiumsoxidcoating med en tykkelse på 1 til 8 pm på de cementerede karbidpartikler.
14. Fremgangsmåde ifølge et hvilket som helst af kravene 11-13, yderligere omfattende trinnet med påføring af en flerhed af lag af coating på de cemen- terede karbidpartikler.
