Description
Foreliggende oppfinnelse vedrører generelt metallskjæringThe present invention generally relates to metal cutting
og mer spesielt slitasjebestandige enkeltlagsbelegg for metallskjæreverktøy. and more particularly wear-resistant single layer coatings for metal cutting tools.
En av hovedtendensene innen moderne metallskjæring er rettet mot forbedringer innen ytelsesegenskaper til slitasjebestandige belegg for metallskjæreverktøy basert på for-bedring av deres kjemiske sammensetning. One of the main trends in modern metal cutting is directed towards improvements in the performance characteristics of wear resistant coatings for metal cutting tools based on the improvement of their chemical composition.
Det er tidligere kjent et slitasjebestandig enkeltlagsbelegg for metallskjæreverktøy (kfr. US patent nr. 4.169.913, A wear-resistant single-layer coating for metal cutting tools is previously known (cf. US patent no. 4,169,913,
Cl. 428-217, 1979) ,. som i det vesentlige er en forbindelseCl. 428-217, 1979) ,. which is essentially a compound
av hafnium med elementene valgt fra gruppen C, N, 0.of hafnium with the elements selected from the group C, N, 0.
Det nevnte belegg kan imidlertid p.g.a. et stort omfang av hafniumioner i praksis bare påføres på sementkarbidmetall-skjæreverktøy. However, the aforementioned coating can, due to a large amount of hafnium ions in practice is only applied to cemented carbide metal cutting tools.
Et ytterligere tidligere kjent slitasjebestandig enkeltlagsbelegg for metallskjæreverktøy (kfr. US patent nr. 4.264.682, Cl. 428-336, 1981) er en fast oppløsning av forbindelsene A further previously known wear-resistant single layer coating for metal cutting tools (cf. US Patent No. 4,264,682, Cl. 428-336, 1981) is a solid solution of the compounds
av overgangsmetaller fra gruppe IV (hvorav ett er hafnium), med karbon og/eller nitrogen. of transition metals from group IV (one of which is hafnium), with carbon and/or nitrogen.
Belegget inneholder titan som det andre overgangsmetalletThe coating contains titanium as the second transition metal
fra gruppe IV som utgjør en del av forbindelsen med karbon og/eller hydrogen. from group IV which forms part of the compound with carbon and/or hydrogen.
Nevnte belegg utviser imidlertid et relativt høyt nivå med hensyn til fri egenenergi, hvilket resulterer i reaksjon av belegget med det materiale som bearbeides og således gir uheldig påvirkning av beleggets slitasjebestandighet. Said coating, however, exhibits a relatively high level with regard to free self-energy, which results in reaction of the coating with the material being processed and thus adversely affects the wear resistance of the coating.
Hovedformålet med foreliggende oppfinnelse er tilveie-bringelse av et slitasjebestandig enkeltlagsbelegg for metallskjæreverktøy, som inneholder et overgangsmetall fra gruppe IV i form av dets forbindelser med nitrogen og/eller karbon som en del av en fast oppløsning som også innbefatter hafnium som forbindelser med nitrogen og/eller karbon, og som vil forbedre beleggets slitasjebestandighet. The main purpose of the present invention is to provide a wear-resistant single-layer coating for metal cutting tools, which contains a transition metal from group IV in the form of its compounds with nitrogen and/or carbon as part of a solid solution which also includes hafnium as compounds with nitrogen and/or or carbon, and which will improve the wear resistance of the coating.
Nevnte formål oppnås på grunnlag av det faktum at et slitasjebestandig enkeltlagsbelegg for metallskjæreverktøy, hvilket belegg er en fast oppløsning-"av forbindelser av to gruppe IV-overgangsmetaller (hvorav ett er hafnium) med karbon og/eller nitrogen, ifølge oppfinnelsen inneholder«^rirkonium som det andre gruppe IV-overgangsmetallet i form av dets forbindelser med karbon og/eller nitrogen. Said object is achieved on the basis of the fact that a wear-resistant single-layer coating for metal cutting tools, which coating is a solid solution of compounds of two group IV transition metals (one of which is hafnium) with carbon and/or nitrogen, according to the invention contains as the other group IV transition metal in the form of its compounds with carbon and/or nitrogen.
Foreliggende oppfinnelse bidrar til å redusere nivået avThe present invention helps to reduce the level of
fri egenenergi i belegget og øker således dets slitasjebestandighet. free intrinsic energy in the coating and thus increases its wear resistance.
Beste måte for utførelse av oppfinnelsen:Best Mode for Carrying Out the Invention:
Det slitasjebestandige enkeltlagsbelegg kan påføres på metallskjæreverktøy på følgende måte. The wear-resistant single-layer coating can be applied to metal cutting tools in the following way.
Et metallskjæreverktøy fremstilt fra et hvilket som helstA metal cutting tool made from any
av de hittil benyttede basislegeringer for verktøy anbringes under vakuum hvor hafnium og 4firkonium fordampes og ioniseres. Deretter forvarmes verktøyets basismetall og dets arbeidsoverflate renses ved bombardering med sirkonium- og hafniumioner. Deretter tilsettes karbon og/eller nitrogen, og dette bringes til å reagere med hafnium og sirkonium, hvilket resulterer i dannelse av en fast oppløsning av deres forbindelser, idet oppløsningen oppretter et slitasjebestandig enkeltlagsbelegg på verktøyoverflaten. of the base alloys used so far for tools are placed under vacuum where hafnium and 4-firconium are vaporized and ionized. The tool's base metal is then preheated and its working surface is cleaned by bombardment with zirconium and hafnium ions. Carbon and/or nitrogen are then added and this is reacted with hafnium and zirconium, resulting in the formation of a solid solution of their compounds, the solution creating a wear-resistant single layer coating on the tool surface.
For en bedre forståelse av foreliggende oppfinnelse gis følgende illustrerende eksempler av praktisk utførelse. For a better understanding of the present invention, the following illustrative examples of practical implementation are given.
Eksempel 1Example 1
20 stålbord med en diameter på 5 mm og med følgende prosentvise sammensetning: 20 steel tables with a diameter of 5 mm and with the following percentage composition:
og som på forhånd er blitt renset for smuss, anbringes i en spesiell beholder som plasseres i et vakumkammer, hvori det også er anordnet en katode bestående av like deler sirkonium og hafnium. Det tilveiebringes deretter et undertrykk på -3 and which has previously been cleaned of dirt, is placed in a special container which is placed in a vacuum chamber, in which a cathode consisting of equal parts zirconium and hafnium is also arranged. A negative pressure of -3 is then provided
1,33 x 10 Pa i kammeret hvorved det opprettes en elektrisk bue slik at sirkonium og hafnium kan fordampe og ionisere. 1.33 x 10 Pa in the chamber, whereby an electric arc is created so that zirconium and hafnium can vaporize and ionize.
En negativ spenning påsettes borene for å akselerere de positivt ladede sirkonium- og hafniumionene, hvorved borenes arbeidsoverflate bombarderes med ionene av nevnte metaller for rensing og forvarming av verktøyenes basismetall. Deretter blir spenningen som er påført borene, redusert, og nitrogen gis adgang til vakuumkammeret for å reagere med hafnium og sirkonium med resulterende dannelse av et slitasjebestandig enkeltlagsbelegg på borenes overflate, idet belegget består av en fast oppløsning av hafnium- og sirkoniumforbindelser med nitrogen. Til slutt fjernes de ferdigbehandlede borene fra vakuumkammeret. A negative voltage is applied to the drills to accelerate the positively charged zirconium and hafnium ions, whereby the working surface of the drills is bombarded with the ions of the aforementioned metals to clean and preheat the base metal of the tools. The voltage applied to the drills is then reduced, and nitrogen is admitted to the vacuum chamber to react with hafnium and zirconium resulting in the formation of a wear-resistant single layer coating on the surface of the drills, the coating consisting of a solid solution of hafnium and zirconium compounds with nitrogen. Finally, the finished drills are removed from the vacuum chamber.
Det således oppnådde belegg har blitt testet for slitasjebestandighet (varighet) ved boring av hull med en dybde på The thus obtained coating has been tested for wear resistance (durability) when drilling holes with a depth of
15 mm i en titan-aluminiumlegering med følgende prosentvise sammensetning: Al - 5, idet Ti utgjør resten, i en opprett-stående søyleboremaskin med rikelig tilførsel av kjølemiddel (10% vandig emulsjon), under følgende skjærebetingelser: 15 mm in a titanium-aluminium alloy with the following percentage composition: Al - 5, with Ti making up the rest, in an upright column drilling machine with an abundant supply of coolant (10% aqueous emulsion), under the following cutting conditions:
hvor S er hastigheten på boret som føres inn i den titan-legering som bearbeides, og v er borets rotasjonshastighet. where S is the speed of the drill that is fed into the titanium alloy being machined, and v is the rotation speed of the drill.
Boret ansees for å ha blitt sløvt når det begynner å gi fra seg pipelyder. Testresultatene ..har vist at varigheten for borene med foreliggende belegg øker fra 8 minutter til 24 minutter i gjennomsnitt sammenlignet med ubelagte bor. The drill is considered to have become dull when it starts making beeping sounds. The test results ..have shown that the duration of the drills with the present coating increases from 8 minutes to 24 minutes on average compared to uncoated drills.
Eksempel 2Example 2
Borene forsynt med et slitasjebestandig enkeltlagsbelegg som beskrevet i eksempel 1, ble benyttet. Samtidig med spennings-reduksjon på borene innføres acetylen i vakuumkammeret med det resultat at acetylenkarbonet begynner å reagere med hafnium og sirkonium for dannelse av et belegg på overflaten av borene, idet belegget består av en fast oppløsning av hafnium og sirkonium med karbon. The drills provided with a wear-resistant single-layer coating as described in example 1 were used. At the same time as voltage reduction on the drills, acetylene is introduced into the vacuum chamber with the result that the acetylene carbon begins to react with hafnium and zirconium to form a coating on the surface of the drills, the coating consisting of a solid solution of hafnium and zirconium with carbon.
Belegget ble testet for slitasjebestandighet som i eksempel 1. Testresultatene viste at varigheten for borene øker fra 8 til 30 minutter i gjennomsnitt sammenlignet med ubelagte bor. The coating was tested for wear resistance as in Example 1. The test results showed that the duration of the drills increases from 8 to 30 minutes on average compared to uncoated drills.
Eksempel 3Example 3
Man benyttet bor forsynt med slitasjebestandig enkeltlagsbelegg som beskrevet i eksempel 1. Samtidig med reduksjon av spenningen som ble påført borene, ble en blanding av acetylen og nitrogen innført i vakuumkammeret, hvorved karbon og nitrogen reagerer med hafnium og sirkonium for dannelse av et belegg på overflaten av borene, idet belegget består av hafnium- og sirkoniumforbindelser med nitrogen og karbon. Drills provided with a wear-resistant single-layer coating were used as described in example 1. At the same time as the voltage applied to the drills was reduced, a mixture of acetylene and nitrogen was introduced into the vacuum chamber, whereby carbon and nitrogen react with hafnium and zirconium to form a coating on the surface of the drills, as the coating consists of hafnium and zirconium compounds with nitrogen and carbon.
Belegget ble testet for slitasjebestandighet som i eksempel 1. The coating was tested for abrasion resistance as in example 1.
Testresultatene viste at varigheten for de belagte bor øker fra 8 til 35 minutter sammen-iignet med ubelagte bor. The test results showed that the duration for the coated bits increases from 8 to 35 minutes compared to uncoated bits.
