Diffusionsbeschichtete, verschleißfeste Bauteile Anwendungsgebiet der Erfindung Die Erfindung betrifft diffusionsbeschichtete, verschleißfeste Bauteile, die als Umformwerkzeuge, Schnittwerkzeuge, 1?ührungseinrichtungen und Verschleißteile hohen mechanischen Beanspruchungen ausgesetzt sind und eine relativ lange Lebensdauer erreichen sollen. Diese Bauteile können überall dort eingesetzt werden, wo Stahl- oder Eisenwerkstoffe solchen Verschleißmechanismen wie Adhäsion, Tribooxidation oder Abrasion unterworfen sind. Auch beim Verschleiß durch Oberflächenzerrütung können unter Umständen positive Ergebnisse beim Einsatz solcher beschichteten Bauteile erreicht werden.Diffusion-coated, wear-resistant components Area of application of the invention The invention relates to diffusion-coated, wear-resistant components, as forming tools, cutting tools, guide devices and wear parts are exposed to high mechanical loads and have a relatively long service life should achieve. These components can be used wherever steel or ferrous materials such wear mechanisms as adhesion, tribo-oxidation or are subject to abrasion. Also in the case of wear due to surface disruption may possibly have positive results when using such coated components can be achieved.
Charakteristik der benannten technischen Lösungen Es sind eine Reihe von Borierverfahren bekannt, mit aenen mittels fester, flüssiger oder gasförmiger, borabgebender Komponenton auf Bauteilen aus Eisen oder Stahl Boridschichten aufgebracht werden können. Diese Boridschichten bestehen vorwiegend aus Zweiphasen, nämlich der T'ieB und Fe2B-Phase, wobei sich diese Zweiphasigkeit nachteilig auf das Verschleißverhalten der aufgebrachten Boridschichten auswirkt.Characteristics of the named technical solutions There are a number of them known from boriding processes, with aenes by means of solid, liquid or gaseous, Boron-releasing component clay applied to components made of iron or steel Boride layers can be. These boride layers exist mainly from two phases, namely the T'ieB and Fe2B phase, this two-phase being disadvantageous the wear behavior of the applied boride layers.
Denn hierbei entstehen zwischen den beiden Phasen Spannungen, die zu Rissen und Abplatzungen führen0 Mit diesem Borierverfahren wurden bisher Schichtdicken bis erreicht , wobei besonders bei dickeren Boridschichten die Gefahr der Abplatzungen aufgrund der Zweiphasigkeit zunimmt.Because this creates tensions between the two phases lead to cracks and flaking0 With this boriding process, layer thicknesses until reached, with the risk of flaking off, especially with thicker boride layers increases due to the two-phase nature.
Zur Vermeidung dieser Mängel sind Pulverborierverfahren bekannt bei denen einphasige Boridschichten erzeugt werden können9 die darauf beruhen9 das zur Reaktion vorhandene Borpotential durch Zusatz nichtreaktionsfähiger Füllstoffe, wie z. B. Siliziumcarbid, Tonerde bzw. reaktionsfähiger Stoffe, z. B. Fe-Oxid zu reduzieren. Jedoch können auch mit diesen Mitteln einphasige Boridschichten nur mit Schichtdicken bis 320 µm erzeugt werden.To avoid these deficiencies, powder borating processes are known from which single-phase boride layers can be produced9 which are based on9 the for Reaction existing boron potential due to the addition of non-reactive fillers, such as B. silicon carbide, alumina or reactive substances such. B. Fe oxide too to reduce. However, single-phase boride layers can only be used with these means can be produced with layer thicknesses of up to 320 µm.
Ein Nachteil ist hierbei darin zu sehen, daß die geringen Schichtdicken nachfolgend keinen Fertigschleifprozeß zur Erhöhung der Maßgenauigkeit erlaubt Ziel der Erfindung Die Erfindung bezweckt die Nachteile der nach bekannten Verfahren borierten Bauteile zu vermeiden und neben der Standzeiterhöhung eine Wiederverwendung dieser Bauteile zu erreichen Darlegung des Wesens der Erfindung Der Erfindung liegt die Aufgabe zugrunde9 diffusionabeschichtete, verschleißfeste Bauteile mit einer Boridschicht bereitzustellen. die eine mechanische Bearbeitung der Bauteile, sowohl zur Erreichung der geforderten Form- und Maßgenauigkeit als auch die Aufarbeitung bzw. Regenerierung dieser Bauteile für die nächsten Abmessungsgruppen zuläßt.A disadvantage here is that the thin layers subsequently no finish grinding process to increase the dimensional accuracy allowed target of the invention The invention aims at the disadvantages of the known methods Avoid boronized components and, in addition to increasing the service life, reuse them to achieve these components Explain the essence of the invention The invention lies the task is based on 9 diffusion-coated, wear-resistant components with a Provide boride layer. mechanical processing of the components, both to achieve the required form and dimensional accuracy as well as the processing or regeneration of these components for the next dimension groups.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Grundkörper eine Diffusionsschicht aufweist, die aus einer homogenen, einphasigen Boridschicht mit einer Mindestschichtdicke von 320K" m besteht.According to the invention this object is achieved in that the base body has a diffusion layer, which consists of a homogeneous, single-phase boride layer with a minimum layer thickness of 320K "m.
