“…The gas content, gas composition, gas flow rate, and the exposure time of the sample in the gas have a significant impact on the mechanical properties and microstructure of the titanium carbide layer [16]. If the methane content is too high, solid carbon deposition will be formed on the sample surface, which will hinder the further generation of TiC [17]. As the affinity between titanium and oxygen is higher than that between titanium and carbon, thin titanium oxide films have been formed before most experiments, preventing the further diffusion of carbon ions [18].…”

Titanium alloy is widely used as oil drill pipe material because of its light weight, high strength, good toughness, corrosion resistance, fatigue resistance, and good process performance. However, due to its low hardness, poor wear resistance, serious oxidation at high temperature (700 °C), and difficulty in lubrication, in oil and gas field exploration and development drilling, especially in deep wells, high displacement wells, horizontal wells, and highly deviated wells, wear and tear are prone to occur. The application and development of titanium alloys are greatly limited. This paper introduces the research status of the common surface modification technologies of titanium alloys, such as laser cladding, magnetron sputtering, plasma spraying, micro arc oxidation, etc. It points out the improvement effect of various modification technologies on the wear resistance and high-temperature oxidation resistance of titanium alloys and discusses the advantages and disadvantages of various modification technologies. A proposed method for enhancing the wear resistance and high-temperature oxidation resistance of titanium alloys was finally introduced, and its potential for future development was investigated.

“…Boriding in steels generates layers with excellent adhesion [2], mainly due to its columnar morphology [3]. Besides, borided layers present high hardness and, consequently, good wear resistance [4][5][6][7][8][9][10][11][12][13]. One of the boriding challenges is to set the appropriate process parameters to obtain the proper microstructure to withstand a given wear environment.…”

Three different boron amounts were used in this study to control the microstructure, mechanical, and tribological properties of borided cases on AISI 4140 steel. A single Fe2B phase was observed for the lowest boron amount, while both Fe2B and FeB phases were present on the other two boron compositions. The highest surface hardness was observed in the highest boron amount. The scratch tests revealed different cohesive failure mechanisms on the samples, such as arc and chevron tensile cracks, and even chipping was observed for all three-studied boron amounts; it appeared at lower applied loads for the highest boron amount, indicating a likely detachment of the fragile FeB layer. The borided layers presented abrasive wear during the ball-on-flat wear tests. Despite the lower specific wear rate, the surface damage was more severe in the sample with the highest boron amount, due to its brittleness, resulting in lower resistance to surface fatigue.
