A method for producing a dental implant is provided. The method includes the steps of (a) providing a dental implant base body, especially an anchoring pin base body; (b) abrasive blasting of at least one surface portion, which is to be configured with a surface that promotes bone growth, and at least regional application of abrasive blasting agent to the surface portion; (c) at most partial removal of the abrasive blasting agent from the surface portion; and (d) sintering of the dental implant base body together with the abrasive blasting agent remaining on the surface portion.

In a coating method example, a coating is formed on a part precursor by blasting the part precursor with a blast medium. The blast medium includes blasting beads and a coating agent. The part precursor is formed from a polymeric build material, and a hardness of the blasting beads is greater than a hardness of the polymeric build material.

A cutting tool including a rake face, a flank face, and a cutting edge portion, comprising a substrate and an AlTiN layer, the AlTiN layer including cubic Al.sub.xTi.sub.1-xN crystal grains, Al having an atomic ratio x of 0.7 or more and less than 0.95, the AlTiN layer including a central portion, the central portion at the rake face being occupied in area by (111) oriented Al.sub.xTi.sub.1-xN crystal grains at a ratio of 50% or more and less than 80%, the central portion at the cutting edge portion being occupied in area by (111) oriented Al.sub.xTi.sub.1-xN crystal grains at a ratio of 80% or more.

Processes for producing peening media, the peening media produced from such processes, and methods of using such media. Particles are provided having surfaces that are formed of or contain a metal that exhibits solubility for oxygen in a metallic phase so as to increase in surface hardness as a result of solid solution strengthening due to oxidizing of the surfaces of the particles. The particles are subjected to a thermal process in an oxygen-containing atmosphere at a process temperature and for a process duration sufficient to oxidize the surfaces of the particles to increase the surface hardness of the particles while not forming an oxide layer that encases the particles.

The present disclosure presents a method and a system for modifying a surface of a substrate. The method includes an act of abrasive blasting of a part of the surface of the substrate. In the abrasive blasting, an abrasive media is provided to the part of the surface. The abrasive media is carried to the part by a first carrier. The abrasive media collides with the part of the surface and causes abrasion to the part of the surface. In the method, the first carrier includes steam. The steam of the first carrier heats the part of the surface.

A surface treatment method is provided that is capable of raising the slidability of a ceramic surface at low cost using a comparatively simple method. Dimples are formed on a surface of a treatment region, this being a portion of a ceramic surface where surface treatment is to be performed, by ejecting substantially spherical ejection particles having a median diameter of from 1 m to 20 m, together with compressed gas at an ejection pressure of from 0.01 MPa to 0.7 MPa, so as to achieve a value of a fastest decay autocorrelation length of not less than 10. The dimples are formed so as to have a plan view profile with a ratio between a horizontal Feret diameter and a vertical Feret diameter of from 0.7 to 1.43. Thereby a ceramic surface with improved slidability can be obtained regardless of use or non-use of a lubricant.
