PROBLEM TO BE SOLVED: To facilitate operation for carrying out thermal spraying and shorten repairing time in thermal spraying by dividing the damaged part of oven wall of a coke oven carbonization chamber into a plurality of layers and improve workability by making preparation of moving speed patterns of a thermal spraying nozzle which are separately different in divided each layer unnecessary. SOLUTION: In the method for carrying out thermal spraying repair by dividing the damaged part of oven wall of a coke oven carbonization chamber into a plurality of layers in damaged depth direction and successively blowing a thermal spraying material from the lower layer, thermal spraying layer thickness of the divided each layer is determined according to damaged depth of the oven wall damaged part and the each layer is constituted to continue from one end side of the oven wall damaged part to other end and further, layer numbers for dividing the damaged part of the oven wall in the depth direction are determined according to depth of the deepest part of damaged part of the oven wall and layer thickness of each layer is determined so that the moving speed patterns of the thermal spraying nozzle in the divided each layer are equivalent.
