Abstract

The present invention relates to antiwear material and is especially antiwear material for at least fiber cutting blade. It has reasonably designed Co-Cr alloy components, has Co matrix and relatively high Cr content, and has alpha-Cr phase and MC phase to improve antiwear performance. It consists of C 1.8-2.5 wt%, Ni 10-12 wt%, Mo 3-5 wt%, Fe 2-4 wt%, Co 24-28 wt%, Cu 1.2-2.0 wt%, Nb 4-5 wt%, Mn 0.0001-2 wt%, Si 0.0001-2 wt% and Cr the rest. The present invention has high hardness and high antiwear performance.

Description

A kind of artificial fiber cutting blade high-abrasive material
The present invention relates to high-abrasive material, specifically a kind of artificial fiber cutting blade high-abrasive material.
The regenerated fiber cutting is mainly worked in acidic medium with blade, not only will have wear resistance preferably, keeps edge of a knife sharpness, and will have good corrosion resistance, could guarantee its long lifetime like this.The relatively good of usefulness mainly is stellite Stellite series cobalt-based wear resistant alloy at present, as Stellite 6.But the user also wishes and can further improve its work-ing life on the basis of this alloy, when key wherein is to keep the alloy excellent corrosion resisting performance, further improve the wear resisting property of alloy, be embodied on the alloy, will further improve hardness of alloy exactly.
The purpose of this invention is to provide a kind of hardness height, the better artificial fiber cutting blade high-abrasive material of wear resisting property.
Technical scheme of the present invention is: the characteristic that adopts cobalt chromium Co-Cr alloy, appropriate design by alloying constituent, on the basis that keeps the Co matrix, fully improve the chromium Cr content of alloy, utilize α-Cr and MC to substantially improve the wear resistance of alloy mutually, keep excellent corrosion resisting performance, further reduced cost of alloy; Its chemical composition content by weight, by 1.8~2.5 parts in carbon, 10~12 parts in nickel, 3~5 parts of molybdenums, 2~4 parts of iron, 24~28 parts of cobalts, 10~12 parts in tungsten, 1.2~2.0 parts of copper, 4~5 parts of niobiums, 0.0001~2 part in manganese, 0.0001~2 part of composition of silicon, surplus is a chromium.
The present invention has following advantage:
The present invention is a kind of regenerated fiber blade that is used to cut, owing to adopt high-abrasive material Cr base, have the advantages that price is low, hardness is high, solidity to corrosion is good, hardness of the present invention can reach 56 to 59, and have the toughness suitable, and have corrosion resistance (erosion rate of 5% sulfuric acid medium is less than 0.03mm) preferably with Stellite6.
Fig. 1 is a smelting technology route map of the present invention.
Below in conjunction with drawings and Examples the present invention is described in further detail.
The present invention adopts Metal Cr, Co, W, Ni, W, Mo, the Cu of general purity, adopts the normal pressure smelting technology to prepare part, and concrete operational path as shown in Figure 1.
The present invention adopts the characteristic of cobalt chromium Co-Cr alloy, appropriate design by alloying constituent, on the basis that keeps the Co matrix, fully improve the chromium Cr content of alloy, utilize α-Cr and MC to substantially improve the wear resistance of alloy mutually, and kept excellent corrosion resisting performance, further reduced cost of alloy; Its chemical composition content by weight, by 1.8~2.5 parts in carbon, 10~12 parts in nickel, 3~5 parts of molybdenums, 2~4 parts of iron, 24~28 parts of cobalts, 10~12 parts in tungsten, 1.2~2.0 parts of copper, 4~5 parts of niobiums, 0.001~2 part in manganese, 0.001~2 part of composition of silicon, surplus is a chromium.
The embodiment chemical ingredients is as shown in table 1.

The embodiment of the invention all has higher hardness and toughness preferably as can be seen from table 1 and 2.
Comparative example
The chemical ingredients of relevant comparative example (1#, 2#) sees Table 3, and wherein embodiment (1#) is the present invention.
Table 3 (wt%)
Example ??C ??Ni ??Mo ??Fe ??Co ??W ?Cu ?Nb ??Mn ??Si ??Cr
