Abstract
The invention relates to a method for coating a tungsten/nickel/molybdenum/iron/boron carbide multi-element alloy on a tool gear for mine road machinery. The method comprises the following steps: firstly, screening and determining appropriate alloys and metal materials and the proper proportion of the alloys and the metal materials; then carrying out surface thermal spraying on the surface of a parent body, and carrying out superaudio high temperature secondary sintering on the surface of the parent body so as to sinter the surface into the state of remelting; carrying out library entry surface treatment and hard alloy welding on the surface of the parent body, thus obtaining a metal parent body made of multi-element alloy metal materials; and then welding the metal parent body with a hard alloy gear as so to be applied to the production of a tool gear for mine road machinery, wherein the surface of the metal parent body has good toughness and wear resistance. According to the invention, not only can the metal parent body be prevented from failure caused by wearing, but also the service life of the tool gear for the mine road machinery.
Description
Affiliated technical field
The present invention relates to a kind of multicomponent alloy coating process of instrument tooth, the tungsten carbide nickel-molybdenum iron boron complex alloy coating process of instrument tooth of especially a kind of mine highway machinery.
Background technology
At present, coal mining with the higher engineer operation of mechanization degrees such as mechanical coal mining and mining machinery highway machinery in, coal cutting pick and highway machinery often lost efficacy to grind the mode that rotten instrument base metal material comes off carbide alloy and fertile material with instrument teeth such as teeth.Coal cutting pick and mine highway machinery tooth are that stress condition is the harshest in coal-cutting machinery and the mine highway machinery instrument, the perishable tool that service life is the shortest.There are bigger gap in the production of China's coal-mine exploitation and mine highway and exploitation aspect and developed country, do not satisfy the needs of domestic great market.In order to solve this scientific and technical difficult problem, the spy develops the tungsten carbide nickel-molybdenum iron boron complex alloy coating process of a kind of mine highway machinery with the instrument tooth, satisfies the demand of engineer operation.
Summary of the invention
For overcome present highway machinery with the instrument tooth often to grind the deficiency that rotten instrument base metal material lost efficacy modes such as carbide alloy and fertile material come off; the invention provides of the tungsten carbide nickel-molybdenum iron boron complex alloy coating process of a kind of mine highway machinery with the instrument tooth; this method is passed through tungsten carbide; nickel; molybdenum; iron; boron and other metallics are arranged in pairs or groups according to a certain percentage; process thermal spraying treatment and secondary superaudio (intermediate frequency) area of heating surface sintering remelting technology are attached to the parent surface of mine highway machinery with the instrument tooth; make instrument tooth surface friction position be coated with the multicomponent alloy metallics material of good toughness of one deck and wearability; lost efficacy thereby protect parent to be difficult for mill, improved the service life that the mine highway machinery is used the instrument tooth.
The technical solution adopted for the present invention to solve the technical problems is: the tungsten carbide nickel-molybdenum iron boron complex alloy coating process of instrument tooth of a kind of mine highway machinery, at first appropriate alloy and metal material and ratio determined in screening, follow surface heat spray treatment parent surface, the superaudio high temperature secondary sinters remelting into then, after surface treatment storehouse body with carry out the carbide alloy welding.So just can obtain the metal carrier body that a kind of surface has the multicomponent alloy metallics material of good toughness and wearability, again the production that is applied to mine highway machinery usefulness tooth tool be welded in it and hard-metal insert.
The invention has the beneficial effects as follows; by tungsten carbide, nickel, molybdenum, iron, boron and other metallics are arranged in pairs or groups according to a certain percentage; process thermal spraying treatment and secondary superaudio (intermediate frequency) area of heating surface sintering remelting technology are attached to the parent surface of mine highway machinery with the tooth tool; so not only protect parent to be difficult for mill and lost efficacy, and improve the service life that the mine highway machinery is used the tooth tool.
The specific embodiment
Tungsten carbide, nickel, molybdenum, iron, boron and other metallics are arranged in pairs or groups according to a certain percentage; process thermal spraying treatment and secondary superaudio (intermediate frequency) area of heating surface sintering remelting technology are used the parent surface of tooth attached to coal cutting pick and mine highway machinery; make coal cutting pick and mine highway machinery obtain a kind of good toughness and the multicomponent alloy metallics material of wearability with tooth surface friction position; lost efficacy thereby protect parent to be difficult for mill, improved the service life that coal cutting pick and mine highway machinery are used tooth.
Concrete grammar is that appropriate alloy and metal material and ratio determined in screening, and---surface heat spray treatment parent surface---the superaudio high temperature secondary sinters remelting into---is through surface treatment storehouse body and carbide alloy welding.
Claims (1)
1. the tungsten carbide nickel-molybdenum iron boron complex alloy coating process of a mine highway machinery usefulness instrument tooth, it is characterized in that: at first appropriate alloy and metal material and ratio determined in screening, follow surface heat spray treatment parent surface, the superaudio high temperature secondary sinters remelting into then, after surface treatment storehouse body with carry out the carbide alloy welding.
