Definitions
- the present invention relates to a method for coating solid diamond materials according to the preamble of claim 1.
- the invention further relates to a method for producing a machine component with a
- machine component is also understood to mean, in particular, a cutting tool and a tool for machining which are well-known to those skilled in the art
- Embodiments may be present.
- Tools in particular those for machining, with a tool head, a tool shank and with a clamping portion for receiving in a tool holder are known in a variety of forms from the prior art.
- Such tools have in their cutting area on functional area topologies, which are adapted to the specific requirements of the materials to be processed.
- the tools mentioned are those which are designed, for example, as drilling, milling, countersinking, turning, threading, contouring or reaming tools. These may have as a functional area cutting body and / or guide rails, wherein the functional body soldered to a support or z. B. may be formed as a change or indexable insert. In addition, it is usually possible to solder on an indexable insert carrier. Typically, such tool heads have functional areas which provide the tool with high wear resistance in the machining of highly abrasive materials such as Al-Si alloys or rock.
- tool heads are provided with a functional layer comprising a superhard material such as cubic boron nitride (CBN) or polycrystalline diamonds (PCD).
- CBN cubic boron nitride
- PCD polycrystalline diamonds
- Shaped bodies of polycrystalline diamonds and sintering aids to solid
- Such solid PCDs are commercially available and can be soldered to a hard metal substrate, for example, with certain solders in an active soldering process under inert gas or vacuum.
- Diamond crystal surface and solder analyzes on real diamond cemented carbide solder joints have shown that the presence of cemented carbide can adversely affect Ti migration to the diamond surface.
- Vacuum brazing is one of the most promising joining methods for making diamond tools, although one must consider the fact that
- Diamonds at elevated temperatures in air from about 500 ° C and in vacuum from about 1300 ° C begin to decompose why it is crucial to provide a joining method in which these critical temperatures are not exceeded.
- Tillmann et al. The covalent bonding of diamond with its bound electrons is the biggest obstacle to a metallurgical interaction between solder alloy and diamond.
- the prior art by Tillmann et al. Proposes that this obstacle be overcome by using a brazing alloy containing active elements that react chemically directly with the diamond.
- Tillmann et al. to use titanium or other unspecified "refractory metals" for this purpose.
- Tillmann et al. a carbidic reaction which results in the formation of a TiC reaction layer which serves as the key to a wetting reaction, since carbide reaction products also have metallic bonds in the sense of an electron gas.
- carbide reaction products also have metallic bonds in the sense of an electron gas.
- Non-oxide ceramics do not necessarily require diamonds for thermodynamic reasons to have such reactive active metals to promote an interfacial reaction. Tillmann et al. experiment with a Kupferbasislot and a
- US Pat. No. 5,626,909 discloses polycrystalline diamond tool sets that can be soldered to a substrate after coating with an adhesive layer and a protective layer of air.
- the bonding layer is formed by coating (by CVD or PVD) a metal layer of, for example, tungsten or titanium and heat treating to produce a corresponding metal carbide at the interface with the tool insert, ie, the diamonds.
- the protective layer applied in a further step consists of a metal such as silver, copper, gold, palladium, platinum, nickel and their alloys and alloys of nickel with chromium.
- coated abrasive particles can be further processed in air with simple solders.
- Diamond materials can be produced, which can be safely and resiliently soldered under ambient air in a metallic surface or against another diamond surface or glued.
- a coated solid PCD according to claim 15 and a machine component according to figure 18 also solves the problem.
- the present invention describes a
