Abstract
A piston assembly including a piston body having a crown and a skirt, the skirt including at least a major thrust face and a minor thrust face, wherein the piston body defines a bore between the major thrust face and the minor thrust face, and a wear coating applied to the major thrust face and the minor thrust face, the wear coating having a cured thickness of at least about 30 microns.
Claims20
A piston assembly comprising:
- a piston body having a crown and a skirt, said skirt including at least a major thrust face and a minor thrust face, wherein said piston body defines a bore between said major thrust face and said minor thrust face;
- and
- a wear coating applied to said major thrust face and said minor thrust face, said wear coating having a cured thickness of at least about 30 microns.
A method for fitting a piston having a skirt into a corresponding cylinder having a cylinder diameter, said method comprising the steps of:
- applying a wear coating to at least a portion of said skirt;
- curing said wear coating, said cured wear coating having a thickness of at least about 30 microns, wherein a diameter of said coated skirt is greater than said cylinder diameter;
- and
- after said curing step, fitting said piston into said corresponding cylinder to shear at least a portion of said cured wear coating from said skirt.
