Description
Technical Field
The application relates to the technical field of surface engineering, in particular to a method for preparing a silver coating by using an ultra-high-speed laser cladding technology and a product thereof.
Background
The reducing furnace is one of important equipment for producing polysilicon and consists of chassis, furnace body, upper sealing head, electrode, etc.
Generally, the furnace body is usually welded by adopting a silver stainless steel composite plate, and a smooth silver material layer is arranged on the inner side of the furnace body, namely the inner wall of the reduction furnace, for example, the technology of patent publication No. CN1559896A and the like.
The silver coating can be directly prepared on the inner wall of the stainless steel by adopting a cold spraying method, but the bonding strength of the silver coating is lower and can only reach about 50MPa at most because the cold spraying is partial metallurgical bonding, so that the silver coating is easy to fall off.
The ultra-high speed laser cladding is a hot spot method for preparing the coating, and is characterized by complete metallurgical bonding and high coating bonding force. For example, patent specification publication No. CN112342542A discloses a method for ultra-high speed laser cladding of 316L coating on 45 steel parts, comprising S1, pretreatment of 45 steel parts and 316L stainless steel powder; s2, fixing the pretreated 45 steel part in a coordinate system of equipment by adopting a clamp; s3, setting a scanning path, a scanning area shape and a scanning area size of 45 steel parts; s4, introducing 316L stainless steel powder into a laser powder feeder, and carrying out ultra-high-speed laser cladding on the 45 steel part according to a scanning path, the shape and the size of a scanning area to form a 316L coating; and S5, polishing the formed 316L coating. The 316L coating prepared by ultra-high-speed laser cladding on the key position of the 45 steel part has the advantages of high surface evenness, no crack and hole defects, fine crystal grains, uniform thickness, good metallurgical bonding with a matrix, high hardness, good wear resistance, good corrosion resistance, short process period and less material waste.
However, if ultra-high speed laser cladding direct transfer is applied to silver coating preparation, the silver coating quality often does not achieve the desired effect due to the low laser absorptivity of silver itself.
