Abstract
The invention relates to a process for a sealing head with nano-reinforced metal thermal shock performance. The sealing head with the nano-reinforced metal thermal shock performance comprises 50-70% of high-carbon waste steel and 20-30% of graphite block, and is characterized in that the high-carbon waste steel and the graphite block are subjected to crystal grain refinement (adopting a nano-powder and adding a crystal grain growth inhibitor) and nano-reinforcement. The process disclosed by the invention has the following characteristics: the design is scientific, the melting point of a binding phase can be increased because Ti is resistant to a higher temperature and the solid solubility in the binding phase is increased, and the increasing of the melting point contributes to the improvement of the red hardness of the sealing head for Ti(C, N)-based metal.
Description
Technical field
The invention belongs to mechanical field, the end socket technique of a kind of nanometer of enhancing metal thermal shock resistance properties.
Background technology
Compared with traditional WC-Co hard alloy, Ti (C, N) Base Metal has the advantage that：High red hardness, high temperature
Good, the high thermal conductivity of antioxygenic property.These performances cause Ti (C, N) Base Metal be more suitable for the polish to material and
Semifinishing.But, compared with WC-Co hard alloy, the relatively low obdurability of Ti (C, N) Base Metal is but greatly limited
It has been made as the application of cutter material.
The content of the invention
It is an object of the invention to solve above-mentioned the deficiencies in the prior art, in order to solve the above problems, the present invention is carried
Go out the end socket technique of a kind of nanometer of enhancing metal thermal shock resistance properties, take high performance Ti (C, N) metal alkyl materials,
The temperature of Ke Yi Nai Genggao, the increase of solid solubility in Binder Phase.
The purpose of the present invention is aiming at the defect of prior art presence, and inventing a kind of nanometer strengthens metal thermal shock resistance properties
End socket technique, including high-carbon steel scrap 50-70, graphite block 20-30% is characterized in that：High-carbon steel scrap and graphite block pass through
Crystal grain thinning (adopt nanometer powder, and add grain growth inhibitor), nanometer enhancing, optimizing components and coming of new
The utilization (such as SHS technology SHS) of technology can obtain fine grain, high performance Ti (C, N) base
Metal material, the end socket technique to form a kind of nanometer of enhancing metal thermal shock resistance properties is cast by D.C.casting method.
It is characteristic of the invention that：Design science, due to the temperature of Ti Ke Yi Nai Genggao, the increasing of solid solubility in Binder Phase
Plus, the fusing point of Binder Phase can be improved, this is helpful to the red hardness for improving Ti (C, N) Base Metal end socket.
Specific embodiment
The end socket technique of a kind of nanometer of enhancing metal thermal shock resistance properties, including high-carbon steel scrap 50-70, graphite block 20-30%
It is characterized in that：High-carbon steel scrap and graphite block by crystal grain thinning (adopt nanometer powder, and add grain growth inhibitor),
The utilization (such as SHS technology SHS) of nanometer enhancing, optimizing components and coming of new technology can be obtained
Fine grain, high performance Ti (C, N) metal alkyl materials, cast to form a kind of nanometer enhancing metal by D.C.casting method
The end socket technique of thermal shock resistance properties.
The present invention has been shown and described embodiment, for the ordinary skill in the art, it is possible to understand that
Without departing from the present invention principle and spirit in the case of these embodiments can be carried out various changes, modification, replacement and
Modification, the scope of the present invention be defined by the appended.
