Embodiment 1

[0029] Preparation of chrome-plated iron wire and nickel-plated iron wire: take the iron wire whose composition weight percentage is 0.08% for C, 0.25% for Si, 0.35% for Mn, P<0.02%, S<0.025%, and the rest is Fe, and the diameter of the iron wire is 1mm . The volume percentage of the control iron wire in the material is 5%.

[0030] Chromium-plating on the surface of half of the iron wire and nickel-plating on the other half of the iron wire according to the conventional method; respectively form a chromium-plated iron wire and a nickel-plated iron wire, both of which have the same length, and the thickness of the coating is 100 μm;

[0031] According to the conventional method of cleaning ball production, each of the above-mentioned chrome-plated iron wire and nickel-plated iron wire is taken to form a spherical mixed double-wire wire group (two wires are formed at the same time to form a double-wire wire group, and the forming can be done according to the dishwashing method)...

Embodiment 2

[0035] The matrix composition of hemp cast iron material is by weight percentage: C is 2.8%, Si is 2.4%, Mn is 0.4%, Y is 1.2%, P<0.08%, S<0.25%, and the rest is Fe for batching.

[0036] The weight percentage of iron wire components: C is 0.10%, Si is 0.35%, Mn is 0.4%, P<0.02%, S<0.025%, and the rest is Fe. The wire diameter is 2mm. The volume percentage of the control iron wire accounting for the material is 40%.

[0037] According to the conventional method, the surface of half of the above-mentioned iron wires is respectively chrome-plated, and the surface of the other half of the iron wires is plated with cobalt to form chromium-plated iron wires and cobalt-plated iron wires respectively. The lengths of the two are equivalent; the thickness of the coating is 500 microns. The conventional method that cleaning ball is produced makes the two-wire metal wire group that two kinds of metal wires of band plating mix, and the wire group diameter is 15cm.

[0038] The preparati...

Embodiment 3

[0040] The matrix composition of hemp cast iron material is by weight percentage: C is 2.5%, Si is 2.3%, Mn is 0.3%, Y is 0.9%, P<0.08%, S<0.25%, and the rest is Fe for batching.

[0041] The weight percentage of iron wire components: C is 0.09%, Si is 0.29%, Mn is 0.38%, P<0.02%, S<0.025%, and the rest is Fe. The wire diameter is 1.2mm. The volume percentage of the control iron wire accounting for the material is 30%.

[0042] Get above-mentioned half iron wire surface to be chrome-plated respectively according to conventional method, the other half iron wire surface is plated with cobalt, respectively form chrome-plated iron wire and cobalt-plated iron wire, two kinds of coated iron wires are of equal length; the thickness of coating is 300 microns. The conventional method that cleaning ball is produced makes the two-wire wire group that two kinds of metal wires of band plating mix, and the wire group diameter is 12cm.

Abstract

The invention provides a wearable and anticorrosive mottled cast iron material and a preparation method. The wearable and anticorrosive mottled cast iron material has better performance. The preparation method has the advantages of simple process and low production cost, and is suitable for industrial production. The material takes the mottled cast iron as a substrate, metal wire groups formed by iron wires are distributed in the substrate, the diameter of the iron wire is 1-2mm, the diameter of each metal wire group is 10-15cm, and the volume percentage of the iron wire in the material is 5-40%.

Description

technical field [0001] The invention belongs to the field of metal materials, and relates to a wear-resistant and corrosion-resistant mottled cast iron material and a preparation method thereof. Background technique [0002] In the field of metal materials, wear-resistant and corrosion-resistant cast iron has been widely valued as a low-cost wear-resistant and corrosion-resistant material. [0003] Zhang Shangang and others studied the design and preparation of low-alloy anti-wear hemp cast iron in the second phase of casting technology in 2003. The main chemical composition of the test material is called: 2.5% ~ 3.5% C; 1.0% ~ 2.0% Si; 0.5% ~ 1.5% Mn; 0.5% -2.0 % (Ni+Cu); less than 1.0% Cr, Mo. But mottled iron is mainly composed of cementite, which is hard but brittle. The toughness of the material is low. It is not conducive to the improvement of the wear resistance and corrosion resistance of the material. [0004] Application No. CN201010150314.1 discloses a rare ...
