Abstract

CoCrFeNiMnTix (x = 0.5, 1.0, 1.5, 2.0 in atomic ratio) high entropy alloy (HEA) coatings were prepared on 304 stainless steel by laser cladding. Experimental results showed that the CoCrFeNiMnTix HEAs constituent phase evolved from a single FCC phase for the HEA to FCC + BCC + Intermetallic + Laves phases with the addition of Ti element. The CoCrFeNiMnTix coatings exhibited an increasing microhardness from 412.42 HV to 573.97 HV. Accompanying the increase in microhardness, the wear resistance was proportional to the hardness of the coating, which met Archard's relationship. In addition, the corrosion resistance of the CoCrFeNiMnTix coatings displayed an increased tendency firstly and then decreased with the addition of Ti element. And, the HEA coating with x = 1.0 possessed the highest corrosion resistance as indicated by the lower corrosion current density, high charge transfer resistance and high pitting potential.

Abstract

CoCrFeNiMnTix(x?=?0.5, 1.0, 1.5, 2.0 in atomic ratio) high entropy alloy (HEA) coatings were prepared on 304 stainless steel by laser cladding. Experimental results showed that the CoCrFeNiMnTixHEAs constituent phase evolved from a single FCC phase for the HEA to FCC?+?BCC?+?Intermetallic?+?Laves phases with the addition of Ti element. The CoCrFeNiMnTixcoatings exhibited an increasing microhardness from 412.42?HV to 573.97?HV. Accompanying the increase in microhardness, the wear resistance was proportional to the hardness of the coating, which met Archard's relationship. In addition, the corrosion resistance of the CoCrFeNiMnTixcoatings displayed an increased tendency firstly and then decreased with the addition of Ti element. And, the HEA coating with x?=?1.0 possessed the highest corrosion resistance as indicated by the lower corrosion current density, high charge transfer resistance and high pitting potential.

13. Ecumenical and Traditioned Measurement: Measuring Christian Maturation Across Distinct Traditions of Christian Spirituality

Abstract

The aim of this article is to explore some of the challenges of measuring Christian spiritual development across distinct traditions of Christian spirituality. This presses into questions of what might be universal and what might be particular when it comes to Christian spirituality in how it is understood and practiced. We address the feasibility of a general, ecumenical measure by hearing from representative voices of five traditions of Christian spirituality: African American spirituality, Anglican spirituality, Benedictine spirituality, Pentecostal spirituality, and Reformed spirituality. After noting some of the distinctives of these traditions, we conclude with four strategies for navigating the unity and diversity of Christian spirituality in conceptualizing and measuring Christian formation.
