Abstract
Nickel-based Seamless Multi-core Braze Coating Material Abstract The disclosure provides a nickel-based seamless multi-core braze-coating material, comprising several flux cores spaced apart from one another and a pure nickel metal layer surrounding the several flux cores, wherein the flux cores comprise the following components in parts by mass: 35 to 49 parts of a brazing filler metal powder, 46 to 60 parts of a hard phase (containing WC and YG8 in a mass ratio of 1:1), and 5 parts of a brazing flux. The braze-coating material is prepared by: weighing the brazing filler metal powder, the hard phase, and the brazing flux, respectively, placing them into a powder mixer, and mixing them uniformly to obtain and then dry a flux core mixture, taking a pure nickel ingot provided with two or three blind holes at an end thereof, adding the dried flux cores to the blind holes, compacting the dried flux cores by vibration until the dried flux cores are compacted at a density of 7.8 to 8.2, and forming a nickel-based multi-core braze-coating material by hot-extrusion, rolling, and drawing. In the disclosure, a nickel-based brazing filler material is composed of an outer pure nickel metal skin and a plurality of inner cores containing a small amount of a metal powder, thereby reducing oxidation when only a powdered brazing filler material is used and facilitating the wetting and spreading of the brazing filler material on the hard phase and on the base material. Moreover, the braze-coating material in the disclosure may be made into a disk or reel shape, and automatic production can be achieved during the braze coating procedure.
Description
Nickel-based Seamless Multi-core Braze Coating Material
Cross-reference to Related Application [0001] The present disclosure claims the priority to the Chinese patent application with the filing number 2019109928795 filed with the Chinese Patent Office on October 18, 2019 and entitled “Nickel-based Seamless Multi-core Braze Coating Material”.
Technical Field [0002] The present disclosure relates to the technical field of brazing materials, and in particular to a nickel-based seamless multi-core braze coating material.
Background Art [0003] High-performance PDC drills, tools, molds, and wear-resistant parts are all required to have high wear resistance and corrosion resistance. If the part is made of an integrated wear-resistant alloy or corrosion-resistant material, not only the cost is high, but also the overall mechanical properties often cannot meet the requirements. A reasonable solution is proposed to apply a layer of wear-resistant or corrosion-resistant metal or alloy to the surface of the part using a surface technology. For forming a wear-resistant layer, commonly used methods comprise physical vapor deposition (PVD) method, chemical vapor deposition (CVD) method, thermal spraying method, surfacing welding method, and braze coating method. The physical vapor deposition method and the chemical vapor deposition method can only result in very thin coatings, which are relatively expensive and are greatly limited in use. The thermally sprayed coating is a mechanically interlocked coating which is poorly bonded with the substrate. The surfacing welding involves heating at a higher temperature, which easily causes thermal stress and deformation and leads to poor surface formability. A brazed coating obtained by the braze coating method is metallurgically bonded with the base material, and the bonding strength is much higher than the mechanical bonding in thermal spraying; the braze coating involves heating at a lower temperature and thus causes less thermal stress and less change in properties of the base material than the surfacing welding; and the brazed coating has a smooth surface, is constructed with high accuracy, and can reach the required accuracy by being less processed.
[0004] The braze coating material consists of two parts, wherein one part is a common brazing filler alloy, which has a lower melting temperature, and is generally called a low melting point component; and the other part is a hard alloy with a high melting point, which is generally called a high melting point component. In theory, any brazing filler material can constitute the low melting point component of the braze coating material. However, as a wear-resistant layer, the brazing filler material itself is required to have a certain hardness and
2020100570 15 Apr 2020 not to be soft. Currently, nickel-based brazing filler materials are commonly used. The nickel-based brazing filler material is hard, brittle, and poor in processibility, and can hardly be processed into a wire-shaped or strip-shaped brazing filler material. In the traditional practice, the nickel-based brazing filler material is firstly made into a powdered brazing filler material, and then is used together with hard alloy particles, binder, organic materials to prepare a braze coating material in a form of suspended slurry, which is coated or adhered to a surface of a workpiece. In order to prevent the oxidation of the base material and the brazing filler material, facilitate the wetting and spreading of the brazing filler material on the surfaces of the hard alloy particles and the base material, it is often necessary to continuously add brazing flux during the braze coating procedure, which results in low work efficiency and easily causes a large waste of the brazing flux and higher cost.
Summary [0005] In order to solve the above-mentioned problems, the disclosure provides a nickel-based seamless multi-core braze coating material, by which the problems of severe oxidation of the slurry braze coating material, low braze coating efficiency, and a large waste of the brazing flux can be effectively solved.
[0006] The disclosure is implemented by the following technical solutions:
[0007] A nickel-based seamless multi-core braze coating material, the braze coating material comprising several flux cores spaced apart from one another and a pure nickel metal layer surrounding the several flux cores, wherein the flux cores comprise the following components in parts by mass: 35 to 49 parts of a nickel-based brazing filler metal powder, 46 to 60 parts of hard phase particles, and 5 parts of a brazing flux.
[0008] Further, the nickel-based brazing filler metal powder may have a particle size of 150 meshes to 200 meshes.
[0009] Further, the nickel-based brazing filler metal powder may be a powder of metals other than Ni element in a nickel-based brazing filler material.
[00010]Further, the hard phase particles may comprise WC particles and YG8 in a mass ratio of 1:1.
[00011]Further, the WC particles may have a particle size of 60 meshes to 80 meshes, and the YG8 may have a particle size of 100 meshes to 120 meshes.
[00012]Further, the brazing flux may comprise a mixture of borax and calcium fluoride in a mass ratio of 85:15.
[00013]A method of preparing a nickel-based seamless multi-core braze coating material, comprises the following steps:
2020100570 15 Apr 2020 a first step of weighing the nickel-based brazing filler metal powder, the hard phase particles, and the brazing flux according to the masses described above, respectively, placing them into a powder mixer, and mixing them uniformly to obtain a flux core mixture for later use;
a second step of drying the flux core mixture prepared in the first step at a temperature of 100 °C to 150 °C for 1.5 to 2 hours to prepare dried flux cores for later use;
a third step of taking a pure nickel ingot, drilling several blind holes uniformly at the center of an end surface of the pure nickel ingot, adding the dried flux cores prepared in the second step to the blind holes, and compacting the dried flux cores by vibration until the dried flux cores are compacted at a density of 7.8 to 8.2 to obtain a pure nickel ingot filled with several dried flux cores for later use; and a fourth step of forming a nickel-based seamless multi-core braze coating material by hot-extruding, rolling, and drawing the pure nickel ingot filled with several dried flux cores.
[00014] Further, the number of the blind holes may be 2 or 3.
[00015]0ne or more embodiments of the disclosure may have, for example, the following advantageous effects:
(1) In the disclosure, a braze coating material may be composed of an outer pure nickel metal layer and a plurality of inner flux cores, which not only overcomes the difficulty of processing a nickel-based brazing filler material into wires or strips, but also alleviates the problem of oxidation when only a powdered nickel-based brazing filler material is used, thereby improving the braze coating effect of the braze coating material.
(2) This braze coating material is provided therein with a brazing flux. The quantitative and automatic addition of the brazing flux can be achieved in the braze coating procedure, and the braze coating quality can be effectively ensured during the braze coating procedure.
(3) In the disclosure, the addition of WC and YG8 at a certain ratio helps to reduce the occurrence of coating cracks and form a dense coating.
(4) This braze coating material may be coiled into a disk or reel shape, and automatic production can be achieved during the braze coating procedure.

Detailed Description of Embodiments [00019]The technical solutions in the embodiments of the disclosure will be clearly and completely described below with reference to the accompanying drawings of the disclosure.
First Embodiment:
[00020]A nickel-based flux-cored braze coating material comprises several (or a plurality of) flux cores 2 spaced apart from one another and a pure nickel metal layer 1 surrounding the several flux cores, wherein the flux cores are compacted at a density of 7.8 to 8.2; the flux cores comprise the following components in parts by mass: 35 parts of a metal powder of elements other than Ni element in a BNi-2 brazing filler material, 46 parts of hard phase particles, and 5 parts of a brazing flux, and the hard phase particles comprise WC particles and YG8 (a WC-Co material containing 8 wt.% of cobalt) in a mass ratio of 1:1. Compared with braze coating materials made of hard phase particles containing only WC particles, the braze coating material, prepared from hard phase particles to which WC particles and YG8 are added, helps to reduce the occurrence of coating cracks and form a dense coating, and exhibits the best effect when the mass ratio of WC particles to YG8 is 1:1. The brazing flux comprises a mixture of borax and calcium fluoride in a mass ratio of 85:15. The pure nickel metal layer 1 is made of a pure nickel ingot.
[00021]The nickel-based seamless multi-core braze coating material is prepared by using the “FCWM50” passive drawing flux-cored welding wire machine, which specifically comprises the following steps:
a first step of weighing the nickel-based brazing filler metal powder, the hard phase particles, and the brazing flux according to the masses described above, respectively, placing them into a powder mixer, and mixing them uniformly to obtain a flux core mixture for later use;
a second step of drying the flux core mixture prepared in the first step at a temperature of 100 °C to 150 °C for 1.5 to 2 hours to prepare dried flux cores for later use;
a third step of taking a pure nickel ingot, drilling three blind holes uniformly at the center of an end surface of the pure nickel ingot, adding the dried flux cores prepared in the second step to the blind holes, and compacting the dried flux cores by vibration until the dried flux cores are compacted at a density of 7.8 to 8.2 to obtain a pure nickel ingot filled with several dried flux cores for later use; and a fourth step of forming a nickel-based seamless multi-core braze coating material by hot-extruding, rolling, and drawing the pure nickel ingot filled with several dried flux cores.
2020100570 15 Apr 2020 [00022]The mass of the pure nickel ingot provided with three blind holes is equal to the mass of Ni element in the BNi-2 brazing filler material.
[00023]Here, the amounts of the respective components of the braze coating material are calculated by the following methods: a pure nickel ingot provided with three blind holes is taken and weighed to have a mass of 1229.6 grams (i.e., the mass of nickel in the nickel-based brazing filler material). The nickel-based brazing filler material to be obtained is selected from a BNi-2 brazing filler material, thus nickel is contained in a mass percentage of 85.4. The mass of the BNi-2 brazing filler material can be calculated to be 1439.8 grams according to the mass of nickel. It can be obtained, from the mass of the BNi-2 brazing filler material minus the mass of nickel, that a nickel-based brazing filler metal powder with a mass of 210.2 g should be added. Then, the mass of the braze coating material is calculated to be 4113.7 g based on the fraction of the BNi-2 brazing filler material in the entire braze coating material which is assumed to be 35 parts. Then, if the hard phase particles are contained in a mass percentage of 50 parts, the hard phase particles have a mass of 2056.85 grams, of which WC and YG8 are in a ratio of 1:1 and each have a mass of 1028.425 grams. The brazing flux is contained in a mass percentage of 5 parts, and thus the brazing flux powder has a mass of 205.68 grams. Hence, it can be calculated that the blind holes shall be filled with 2472.73 grams of a flux powder, which is exactly equal to or slightly lower than the mass of compacted flux powder having a volume equal to the volume of the blind holes provided in the pure nickel ingot.
[00024]35CrMo tool steel was selected and used as the base material. An abrasive wear test was performed on the product of this embodiment. The abrasive wear test was performed on an MLG-130A dry rubber wheel abrasive wear tester. The brazed coating size was 40 mm χ 25 mm χ 6 mm. The test was performed at a load of 20 N, using 120 # brown corundum sand as an abrasive, at a rubber wheel rotational speed of 100 r/min, and at a sand flow rate of 100 g/min, and the wear test was carried out for 15 min. The wear of the coating was expressed as loss in mass, the test result of which was 37 mg. The traditional suspended slurry braze coating material, prepared from the substances such as BNi-2 brazing filler material powder and cast tungsten carbide powder in the same ratio, exhibited a test result of 48 mg in the same braze coating process and in the same abrasive wear test. This braze coating material showed significantly higher wear resistance than the traditional powdered braze coating material.
