摘要:
An article having a slip-resistant surface and method of producing the same includes metallurgically bonding raised bead-like configurations of a compatible material at select locations on the article surface. The method includes injecting, substantially simultaneously with projecting a high power radiant energy beam, powder particles into a portion of the beam lying a distance away from the point of impingement on the surface portion of the article. The particles interact with the beam for a time period sufficient to cause at least partial melting of a substantial number of particles which are then transported to a selected point on the surface portion. The partially melted particles, along with completely and/or any substantially unmelted particles, are allowed to bond with the surface material thereby forming a raised configuration thereon. The process is repeated for forming another raised configuration at another selected location on the surface portion for thereby forming a slip-resistant article. The configurations include an upright portion of substantially all sintered particles and extending a substantial distance above the surface portion, and an anchor portion which is embedded a slight distance into the surface portion and includes a weld of the base material uninterrupted with the sintered particles. The anchor portion has a height dimension which is substantially less than the height dimension of the configuration.
