In this review article, many aspects of high-temperature hydrogen attack steel are examined in a practical, topic-based format similar to that API RP 571. This article is result reviewing over 220 articles on the subject, published mostly between 1938 and 2020, while some them were already citing research going back late nineteenth early twentieth centuries. The paper not only examines historic...

Abstract WC-Co coatings sprayed by HVOF attracted much attentions, benefiting from the satisfactory wear resistance and high bonding strength to steel substrates. Nevertheless, density of conventional required excessive Co binder, which decreased hardness operation life. Based on this, a strengthened WC-30WB-10Co coating was developed with both improved hardness, using high-qualified thermal co...
