Analysis On The Finishing Of Alumina Ceramic Surface Finish And The Strengthening Of Its Mechanical Strength

Today,the editor of Alumina Ceramics has learned for you the finishing of alumina ceramic surface finish and the strengthening of its mechanical strength.

In order to improve the accuracy of the product,after finishing the sintering process,most alumina ceramic materials need to be further processed to achieve a higher surface finish.But alumina ceramic is not an ordinary material after all,how can its finishing process be better?

Because the hardness of alumina ceramic material is relatively good,it needs to be processed with harder grinding and polishing brick materials,such as SIC,B4C or diamond drill,etc .; and in the process of finishing,the alumina ceramic material must be improved in advance Surface lubricity.

In the finishing of alumina ceramic materials,the more common method is to grind from coarse to fine abrasives step by step,and then perform surface polishing.When polishing,you can use Al203 fine powder or diamond diamond paste less than 1μm to polish and polish.Processing and ultrasonic processing can also achieve the purpose of grinding and polishing alumina ceramics.

The above is a finishing process for improving the surface finish of the alumina ceramic material,and then a treatment for enhancing the mechanical strength of the alumina ceramic,that is,the alumina ceramic strengthening technology.In fact,advanced technology such as electron ray vacuum coating,sputtering vacuum coating or chemical vapor deposition is used on the surface of the alumina ceramic to make the alumina ceramic tough.

In these methods,a layer of silicon compound film can be plated on the surface of the alumina ceramic,and the alumina ceramic can be tempered only by heating at a temperature of 1200 ° C to 1580 ° C.Facts have proved that the mechanical strength of the reinforced alumina ceramics can be greatly increased on the original basis to obtain alumina ceramics with ultra-high strength.
