Description
Technical field
The present invention relates to a kind of polishing fluids of the powder containing polishing, and in particular to one kind is suitable for hard alloy metallographic polishing and uses
Polishing fluid.
Background technology
Metallographic Analysis is one of main method for studying metal and alloy internal structural flaw, in metal material research field
In occupy critically important status.50-1500 times of specimen method can be studied the tissue of metal and alloy by metallographic microscope, be to grind
Study carefully a kind of most basic experimental technique of metal material microstructure.The process of metallographic sample preparation can be divided into several processes, including
Cutting sampling, edge sample, mechanical lapping, four procedures of mechanical polishing.Cutting sampling process cuts the metal sample of required inspection
It takes off, the size for being suitble to inlay is cut into the metal derby analyzed in cutting.Edge sample can be used metallographic pointing machine into
The method that cold edge can also be used in row hot insert is inserted heat cured resin-oatmeal in metal pattern, be analysed to metal sample insertion
In resin-oatmeal, then by heating pressurization to metal pattern or adding in curing agent, make resin-oatmeal curing molding.It is needed pair after the completion of edge sample
Metal sample tested surface is polished, and is then polished, and suitable corrosive liquid is selected to carry out etch or wiping after polishing, is obtained to be measured
The microcosmic grain structure of metal covering.
The purpose of mechanical lapping and polishing is in order to obtain smooth surface, in order to which metal phase after corroding can be complete
Ground is presented in microscope.Plane is milled into sand paper first generally, for metallographic sample, then uses more fine and smooth sand
Paper fine grinding finally carries out rubbing down using antiscuffing paste, metallographic test surfaces is made to reach required by fine rubbing down again and again
Effect.The antiscuffing paste used in the prior art is the common powder such as cerium oxide, chromium oxide as antiscuffing paste, and commercially available antiscuffing paste is mostly
Yellow, during practical metallographic sample preparation, colored polishing powder easily test surfaces are dyed or concealed in metal sample with
The seam crossing of inlay is dissolved out in corrosion, influences the surface effect of corrosion.These antiscuffing pastes are stablized because to ensure simultaneously
Property and uniformity, often lotion is sticky, is not easy to disperse, be difficult in polishing process all be effectively scattered on polishing cloth, cause
Greatly waste, the precision for also be easy to causeing polishing are low, it is impossible to finely be polished.Also have using bortz powder as polishing powder
Antiscuffing paste, but price is extremely expensive.
Invention content
For the shortcomings of the prior art, it is suitable for hard alloy metallographic sample preparation the present invention provides one kind and throws
The polishing fluid of light, the polishing fluid solid particle is fine and smooth and hardness is big, effectively hard alloy finely can be polished, while the throwing
Light liquid good fluidity, it is cheap, metallographic test surfaces will not be caused dyeing perplex.
The technical problems to be solved by the invention are achieved by the following technical programs：
The component and content of Metallographic Analysis polishing fluid in the present invention be：
Alumina powder 200-240g/L
Mullite powder 30-50 g/L
Dodecyl sodium sulfate 8-12 g/L

Polishing powder in the present invention selects the mode that alumina powder is used in combination with mullite powder.The present inventor
When finding to match with mullite powder using alumina powder in practice, to the removal effect ratio of carbide surface fine scratches
Single aluminium oxide will be got well as the effect of polishing powder.Alumina powder is one of common polishing powder, and mullite is silicate
The mineral generated at high temperature, wherein containing stable Al2O3-SiO2Symbiotic compound, Mohs' hardness can reach 8 or so, in right amount
The hardness of alumina powder can not only be effectively promoted after addition, and other mineral elements contained in mullite powder are to polishing
Stable suspersion of the powder in water and ethanol solution has very big facilitation.Meanwhile alumina powder is in white with mullite powder
The problem of color, inclined light gray, easily cleaning removes, sample surfaces will not be caused to dye.
For alumina powder and mullite powder is enable effectively to be scattered in the mixed solution of water and ethyl alcohol, dodecyl sulphur is added
Sour sodium and nonylphenol polyoxyethylene ether improve the surface state of polishing powder, make powder surface that parent be presented as surfactant
Water state makes it be easier to be disperseed in preparation process.Tripolyglycerol monostearates and triethanolamine then can further promote
Into the polishing hydrophilic improvement of powder surface, while it can also adjust the viscosity of polishing fluid in the present invention.Potassium pyrophosphate and trimerization phosphorus
Sour potassium dissolubility is splendid, while the ability for adjusting pH value and conformable metallic ion is strong, and it is whole that appropriate addition helps to maintain polishing fluid
The electric equilibrium type of body makes polishing fluid more stablize.Meanwhile to make the dispersion of polishing fluid each group balance-dividing using water and ethyl alcohol two-component
Decentralized medium.
