technological coating
2.A new type of electroplating satin nickel process is put forward,and the effects of bath compositions and technological parameters to the coating appearance are studied. When using the satin nickel additives (WD 20) obtained from our experiments,a good appearance of satin nickel coating has been obtained in the conditions of medium temperature,wide current density and agitation-free.
3.The results show that, by controlling proper laser technological paramoters, structure can be fined, coating compactness and adhesion can be obviouly enhanced and the composition dilution is very low in the laser-remelting zone.
4.A TiC-Fe cermet graded composite coating on a cast s te el substrate was successfully fabricated by an SHS-casting route. The effects o f technological parameters, such as pouring temperature of liquid steel, composi tion of Ti-C-Fe preform and its relative green density, on the microstructure of the coating were emphatically studied.
5.Abstract Based on the technological process and leather chemicals used in Chrome-vegetable combination Tanned light leather,the auther described how to enhance the grade of finished leather by using suggested coating techniques.
6.Technological properties of phosphate cold-setting sand with acid-phosphate as the bonding agent,and C 2S as the setting agent were tested,and productional application was done, and productional application was done. It has proved that the good technical and practical properties of the coating can be obtained.
7.During the process of reformation, for stating the appropriate casting parts should be selected, the quality of pattern and coating should be strictly controlled, and the flask and vibrating platform need to be reasonably chosen according to its technological characterizations.
8.Cast Cu alloys were used in the dental repairs, and a Ni-P amorphous coating was electroless deposited onto the surface to prevent corrosion. Sush a material used as an alternative of the conventional gold base alloy and the high-melting point, high shrinkage Ni-Cr, Co-Cr dental alloys have opened up a new approach for the dental plastic techniques. Clinical practice has proved that these materials possess good technological and service properties, and are also cheap in cost.
