Description

A kind of method that improves growth speed of titanium alloy microarc oxide film
Technical field
The present invention relates to a kind of raising oxide growth method of velocity, relate in particular to a kind of method that improves growth speed of titanium alloy microarc oxide film.
Background technology
The middle and later periods nineties 20th century; Differential arc oxidization technique is introduced China by western developed countries such as Russia; It is on the basis of common anode oxidation, to grow up; Adopt high-voltage, high current density, utilize the reaction that arc discharge strengthens and activation upward takes place at anode (titanium alloy, duraluminum and magnesiumalloy etc.), thereby form ceramic coating; Can significantly improve hardness, wear resistance and the solidity to corrosion of matrix alloy, in industries such as space flight, aviation, automobile, electronics and machinery, have great application prospect.
Also do not have unified understanding at present both at home and abroad for the principle of differential arc oxidation, the research of differential arc oxidation is mainly concentrated on adjusting process parameter and solution composition on differential arc oxidation membrane structure and the Effect on Performance both at home and abroad.Research both at home and abroad shows, improves current density, adopts pulse or AC power, can improve the speed of growth of micro-arc oxidation films such as titanium alloy, duraluminum, in differential arc oxidation solution, adds some hard, nonconducting particulate, like Al 2O 3Deng, be similar to composite electroplated plating or electroless plating compound plating, these particulates are mixed in the micro-arc oxidation films, the speed of growth of micro-arc oxidation films is improved, the hardness or the solidity to corrosion of sull improve.
The present invention is nanometer Al powder or the nanometer Cr powder that in titanium alloy differential arc oxidation solution, adds 0.5-6g/L; Through stirring it is uniformly distributed in the solution, because metal nano powder conducts electricity, when it moves to specimen surface arc discharge regional; Can participate in arc discharge; Make arc light in the time lengthening that specimen surface stops, increased the temperature of top layer micro-arc oxidation films, the reaction of matrix alloy differential arc oxidation is quickened; Increased the speed of growth of micro-arc oxidation films, and the participation film forming of very small amount is not participated in or is had at metal powder or its oxide compound end.Do not find also at home and abroad at present that relevant Nano metal powder promotes the research report of differential arc oxidation layer-growth rate, relevant its mechanism also need be furtherd investigate.
Summary of the invention
The object of the present invention is to provide a kind of method that improves growth speed of titanium alloy microarc oxide film; This method is applicable to the speed of growth that improves titanium alloy, duraluminum and magnesium alloy differential arc oxidation film; The resource and the energy during for saving titanium alloy, duraluminum and magnesium alloy differential arc oxidation are significant, in industries such as space flight, aviation, automobile, electronics and machinery, have great application prospect.
The present invention realizes like this, it is characterized in that method steps is:
1) configuration differential arc oxidation solution: the differential arc oxidation solution formula is following: Na 2SiO 36g/L, NaAlO 24g/L and NaOH 1g/L;
