PROCESS FOR MANUFACTURING A FIXING DEVICE |
| 摘要 |
The invention relates to a process for manufacturing a fixing device and a fixing device made by such a process. In particular, albeit not exclusively, the present invention relates a fixing device for application in fixing to concrete and like materials/substrates. The present invention therefore seeks to provide a fixing device for fixing to concrete, other like substrates which overcomes, or at least reduces some of the known problems of the prior art. The present invention also seeks to provide a fixing device which has enhanced corrosion resistance. |

1. A process for manufacturing a fixing device for fixing to concrete and like substrates, the process comprising:
a) selecting a heat treatable steel for forming the fixing; b) rolling the steel to form a fixing product; c) applying a nitriding process so as to penetrate the surface of the steel, whereby to create a surface skin; and, d) applying a Sherardizing diffusion process so as to increase corrosion resistance. |
