Abstract

The invention discloses a special nano-material used for ultra-precision treatment on surface of an aluminum alloy, which comprises the following components by mass ratio: 80-90 parts of silica sol, 4-8 parts of pH conditioning agent, 2-4 parts of activator, 2-4 parts of buffering agent and 2-4 parts of antiseptic. The special nano-material used for ultra-precision treatment on surface of the aluminum alloy has the advantages of non toxicity, no corrosion and difficult deterioration, in a polishing step, different ratios can be optimized according to requirement, so that the processed workpiece has bright and beautiful surface, and has brilliant color, workpiece corrosion can be prevented, the workpiece surface luster of the workpiece is increased, and thereby the optimum usage effect can be reached.

Description

technical field [0001] The invention relates to a special nanometer material for ultra-precision machining of aluminum alloy surface, in particular to a special nanometer material for ultra-precision machining of aluminum alloy surface. Background technique [0002] In recent years, with the development of high-tech, higher requirements have been put forward for the planarization processing technology with extremely high precision and near defect-free materials, and in some planar devices, key or important parts such as flyers and samples need to be Realize extremely high-precision, near-defect-free ultra-precision planarization processing for certain alloy materials. Due to its excellent performance, aluminum alloy materials have been more and more widely used in the fields of national defense, aviation, aerospace, chemical industry, electronics, and machinery manufacturing, and higher requirements are put forward for their surface perfection. Therefore, it is of great app...
