A producing method for a cylinder block includes: a spraying step of spraying a metallic material onto a bore inner surface of at least one cylinder bore formed in the cylinder block to form a spray deposit thereon; a pressurizing step of applying a predetermined pressure onto a surface of the spray deposit formed on the bore inner surface in the spraying step; and a honing step of applying a honing processing to the surface of the spray deposit after the pressurizing step.

A method includes spraying a coating on to an engine bore surface, honing the coated surface to create a honed surface region, and cleaning the honed surface region to remove material from the surface pores. The honed surface region includes a plurality of surface pores and upper, middle, and lower regions. Cleaning the honed surface region produces upper, middle, and lower region surface porosities, with the middle region porosity being greater than at least one of the upper and lower porosities.

Coating compositions for coating an oilfield operational component, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of the oilfield operational component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.
