Abstract
The invention relates to special polishing fluid for plastic soft metallic materials and a method for preparing the polishing fluid and belongs to the technical field of the polishing fluid. The polishing fluid is prepared from a ground material, a solvent and additives which are in a certain volume ratio, namely 2% of brightener, 3% of diamond micro powder, 15% of additives and 80% of kerosene. The method comprises the steps of: adding the diamond micro powder into melted lard or vaseline, and stirring uniformly; then, adding the kerosene, and cooling down to room temperature for standby; and adding stearic acid particles (C17H35COOH), vegetable oil and spindle oil into a clean vessel, stirring uniformly, adding the brightener, and uniformly mixing and stirring the solution, thereby obtaining the polishing fluid. The surface of a niobium alloy workpiece processed by the polishing fluid is uniform in mass, is free from polishing lines and can reach a mirror polishing effect. Meanwhile, the polishing fluid can play a role in cooling, lubrication, adsorption and washing during processing and can also be applied to the mirror polishing processing of similar plastic soft metallic materials, the operation is simple, the efficiency is high, the cost is low, and no pollution is caused.
Description
Technical field
The invention belongs to polishing fluid technical field, be mainly used in the Ultraprecise polished of plasticity softer metals niobium and alloy thereof, also the Ultraprecise polished of other class quasi-plasticity soft metal materials is applicable to, this polishing fluid advantage is can effectively improve machined surface quality and working (machining) efficiency, cooling, lubrication can also be played in the course of processing simultaneously, the effect of absorption and cleaning, is applicable to the industries such as Aero-Space manufacturing engineering and machine-building.
Background technology
Nb and Nb-based alloys is the excellent characteristics such as intensity is high, plasticity good, corrosion resistance because having, become the novel metal after steel, magnesium, aluminium, be widely used in the fields such as Aero-Space, petrochemical industry, medical treatment, its processing mode and machining accuracy also come into one's own day by day.In it precise polished, usually adopt chemistry or electrochemical processing mode, polishing fluid used is acid solution, is not easy to process uniform surface quality.In chemico-mechanical polishing, the good chemical mechanical polishing liquid of performance must be adopted just to reach the polishing effect of expection, and usual this polishing fluid is expensive.Traditional polishing fluid is general, and again not containing abrasive material, abrasive material is generally embedded in the milling tool softer than workpiece, during grinding, the abrasive material exposed from milling tool easily and polishing fluid mix uneven, the surface processed easily produces lines, and surface accuracy is low.
Summary of the invention
The object of the invention is to for existing common polishing fluid after Nb and Nb-based alloys polishing, finished surface easily produces defect, there is polishing lines, be difficult to reach the problems such as mirror finish effect, and a kind of easily polishing is provided, do not produce polishing lines, the Nb and Nb-based alloys special-purpose polishing liquid of mirror finish effect can be obtained.During use, only need be added on polishing pad by the special-purpose polishing liquid configured, place work piece carries out processing, and simple to operate, efficiency is high, and cost is low, pollution-free.
Plasticity softer metals special-purpose polishing liquid of the present invention, it is characterized in that: abrasive material is mainly the diadust of 0.25 ~ 0.5 μm with particle diameter is abrasive material, solvent is kerosene, additive is mixing fat and industrial lard or vaseline, polishing fluid be by abrasive material, solvent and additive by certain volume ratio: the brightener of 2%, the abrasive material of 3%, 15% additive, 80% kerosene formulated, lubrication, cooling, absorption, cleaning and the effect of surface of the work film forming is played, to obtain best polishing effect in the polished one-tenth of accurate ultra.
Each component volume percentage of additive is controlled according to the ambient temperature difference used:
1., when the ambient temperature used is 5 ~ 15 DEG C, additive is 30% lard, 30% stearic acid particles (C by percent by volume
17h
35cOOH), 20% vegetable oil, 20% bobbin oil composition;
