Abstract:
A method for manufacturing a cylinder block of an internal combustion engine, comprising the steps of:defining a set of parameters for said cylinder block including at least an abrasion resistance layer thickness, a desired welding strain, a first finished bore dimension, a thrust direction, and an anti-thrust direction; forming a cylinder block matching said set of parameters; designating at least a first and a second build-up welding portion along a bore of said cylinder block corresponding to said thrust and said anti-thrust directions; performing build-up welding in said first and said second build-up welding portions; and final finishing said cylinder block to said first finished bore dimension, whereby a surface of said bore retains an abrasion resistant layer having said abrasion resistance layer thickness and said desired welding strain along said thrust and anti-thrust directions.
