NOVELTY - The method involves obtaining the blade array micro-structure. A cutting line of appointed format is drawn based on the blade array micro-structure. The drawing line is introduced into the electric spark processing and cutting system. An electric spark numerical control wire cutting machine is continuously established according to the instruction of the introduced drawing. Electric spark wire cutting process is performed for the processing workpiece surface by an ultrasonic cleaning instrument using ethanol for performing ultrasonic cleaning for 7 min. The workpiece is heat preserved for 450 degrees centigrade for about 60min after cleaning according to the working characteristic of the shape memory alloy. The workpiece with graphene photo-thermal coating is extracted by using the ethanol for ultrasonic cleaning for 7 min. The shape memory alloy substrate with blade array micro-processing is finished. USE - Self-heat-absorbing reshaped ice/deicing micro-array structure preparation method. ADVANTAGE - The method enables reducing self-heat-absorbing reshaped ice/deicing micro-array structure preparation cost, energy consumption, environment pollution and easy corrosion of rubber and metal parts. The method enables reducing the contact area between the ice and the substrate so as to reduce the adhesion strength of the ice on the material surface. The method generates a large amount of heat by photo-thermal conversion and quickly improves the local temperature. The directional rolling of the liquid drop can be realized by adjusting and controlling the array microstructure shape, which is convenient for deicing. DETAILED DESCRIPTION - The shape memory alloy surface is made of nickel-titanium shape memory alloy material DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a self-heat-absorbing replicable deicing/deicing micro-array structure Nickel-titanium shape memory alloy substrate (2)
