Abstract
The invention relates to a preparation method of a steel base surface composite. The WC/high chrome steel base surface composite is prepared by vacuum-evaporative pattern casting (V-EPC).
Description
Technical field
What the present invention relates to is a kind of composite material and preparation method thereof, a kind of steel matrix skin layer composite material preparation method of special design.
Background technology
The method of preparing steel matrix skin layer composite material in conventional art is very loaded down with trivial details, and cost is high.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of method of preparing steel matrix skin layer composite material.
In order to achieve the above object, a kind of steel matrix skin layer composite material preparation method of the present invention, its concrete steps are as follows:
The first step, the preparation of preformed layer: utilize ball mill by after joining in advance enhancing particle, alloy powder in preformed layer and stirring, add appropriate binding agent (the 6wt%PVA aqueous solution) to continue to stir until obtain the preformed layer of paste.This preformed layer is comprised of WC particle, high carbon ferro-chrome powder, binding agent, and WC strengthens particle to be mixed by different volumes mark with high carbon ferro-chrome powder;
Second step, the preparation of Foam Pattern and prefabricated section preset: Foam Pattern is of a size of 40 * 40 * 40mm, and the prefabricated section that is paste is directly coated on 40 * 40mm face, and thickness is 3mm;
The 3rd step, the bonding of running gate system and brushing paint: design running gate system, utilize white glue with vinyl to be linked, preformed layer is all positioned at the basal surface position of cast, all surface brushing 1mm left and right evaporative pattern special coating to sample, and be placed in the interior baking of 50 ℃ of drying ovens 2 hours;
The 4th step, moulding and cast: utilize 40～60 order quartz sands to carry out the moulding of vacuum full mold to whole apperance, smelting metal (base material), molten steel tapping temperature is 1680 ℃, pouring temperature is 1580 ℃, and the vacuum of cast early, middle, late stage is respectively 0.065,0.060,0.062MPa.Watered rear insulation and unpacked for 1 hour, to be cooled to room temperature, sand removal.
The specific embodiment
A preparation method, its concrete steps are as follows:
The first step, the preparation of preformed layer: utilize ball mill by after joining in advance enhancing particle, alloy powder in preformed layer and stirring, add appropriate binding agent (the 6wt%PVA aqueous solution) to continue to stir until obtain the preformed layer of paste.This preformed layer is comprised of WC particle, high carbon ferro-chrome powder, binding agent, and WC strengthens particle to be mixed by different volumes mark with high carbon ferro-chrome powder;
Second step, the preparation of Foam Pattern and prefabricated section preset: Foam Pattern is of a size of 40 * 40 * 40mm, and the prefabricated section that is paste is directly coated on 40 * 40mm face, and thickness is 3mm;
The 3rd step, the bonding of running gate system and brushing paint: design running gate system, utilize white glue with vinyl to be linked, preformed layer is all positioned at the basal surface position of cast, all surface brushing 1mm left and right evaporative pattern special coating to sample, and be placed in the interior baking of 50 ℃ of drying ovens 2 hours;
The 4th step, moulding and cast: utilize 40～60 order quartz sands to carry out the moulding of vacuum full mold to whole apperance, smelting metal (base material), molten steel tapping temperature is 1680 ℃, pouring temperature is 1580 ℃, and the vacuum of cast early, middle, late stage is respectively 0.065,0.060,0.062MPa.Watered rear insulation and unpacked for 1 hour, to be cooled to room temperature, sand removal.
