Form & Roughness of Precision Surfaces – Cylinder Bore

Engine Cylinder Bore Crosshatch Machining

Surface Finish Measurement - Crosshatch Machining Marks

To reduce engine weight and efficiency of today's advancing engines, manufacturers are relying on new plasma transfer technologies coating for cylinder surfaces. While these thermal coatings offer long life and low friction characteristics, they also require careful control and inspection of tribological surfaces.

After application of the coating, a rough, stochastic surface needs to be inspected for pores, remnants of non-overlapped structuring of the plasma deposition. The next step is the honing of the inner cylinder. This creates a stratified surface over which the piston rings can glide and re-distribute lubrication for the smooth operation of the piston.

The angles and depths of these crosshatched patterns play a major role in the prevention of piston seizure and proper operation within the combustion chamber.
