Abstract
A method of manufacturing a component for a turbo machine. The component includes a main body having a fluid inlet and fluid outlet. A cooling passage extends between a fluid inlet and a fluid outlet. The cooling passage is divided into a first and a second section which extend between the fluid inlet and fluid outlet. The first section has a first predetermined roughness; and the second section has a second predetermined surface roughness; the predetermined surface roughness in at least one of the first section and second section is defined by a plurality of spaced apart micro ribs which extend at least part of the way across the cooling passage, at least one of the cooling passage sections is formed to further include macro ribs which extend across the cooling passage, at least one micro rib is being formed between adjacent macro ribs.
