ได้ยินมาว่า Tenifer อยู่ข้างใน ข้างนอกที่เห็นน่ะเคลือบทับอีกที
ใช่ครับ Tenifer เป็นกระบวนการทำผิวให้ทนสนิมอยู่ข้างใน ซึ่งจะไม่มีสีแต่ที่เห็นผิวดำๆเป็นการเคลือบรมดำแบบ"parkerizing"ทับอีกที แต่รุ่นใหม่ๆคงจะทำผิวให้เนียนสวยขึ้น
* The Exterior finish on Glock Pistols
Most of the metal parts on the Glock pistol receive a finish called Tenifer. This finish is applied to a depth of three thousandths of an inch. The Tenifer finish is rated at 69 on the Rockwell hardness scale. About the only thing harder than Tenifer is a diamond or carbide. The Tenifer finish on Glocks carbon steel slide resists corrosion much better than even stainless steel.
If you somehow manage to cut through the Tenifer finish, Glock cannot "Re-Tenifer" your pistol. It would be too brittle and the metal would be subject to cracking.
The finish you see on the exterior of the slide on a new Glock pistol is not the Tenifer finish. The Tenifer is a metal process, and is colorless. The dark exterior metal is a parkerizing type finish applied over the Tenifer finish. As the pistol is used and rubbed over a long period of time, this finish may wear off in spots.
Glock can refinish this "parkerizing" type of finish if you ever use your Glock often enough and long enough to wear it partly off. Contact Glock for details and prices.
