| Citation: | The use of titanium alloys for details of downhole hammers / A. I. Popelyukh [et al.] // IOP Conference Series: Materials Science and Engineering. — 2016. — Vol. 124 : Mechanical Engineering, Automation and Control Systems (MEACS2015) : International Conference, 1–4 December 2015, Tomsk, Russia : [proceedings]. — [012116, 5 p.]. |
| Abstract: | The influence of cementation technology of titanium alloy Ti-Al-Mn on its wear resistance is studied. It is established that after lubrication a friction pair with mineral oil the wear resistance of the cemented titanium alloy is comparable to wear resistance of the tempered steel 12HN3A, and in water medium surpasses it by 1.5 times. Decrease in the tendency to seizure with steel is the main reason for increase of wear resistance of titanium alloy. Industrial tests of the ASH43 hammer have shown that the use of titanium alloys for the manufacture of hammer strikers allows to increase impact capacity by 1.5 times and to increase drilling rate by 30 % compared to hammers with steel strikers. |
