Method of manufacturing component having magnetic and non-magnetic dual phases

Methods of forming a dual-phase magnetic component from an initial component comprising a non-magnetic austenite composition are provided. The method may include forming a coating on a portion of a surface of an initial component to form masked areas while leaving unmasked areas thereon. Thereafter, the initial component may be heated to a process temperature such that nitrogen diffuses out of the unmasked region of the initial component to convert the non-magnetic austenite component into a magnetic phase in the unmasked region. Thereafter, the initial component may be cooled from the process temperature to form a dual-phase magnetic component having a magnetic region corresponding to the unmasked region and a non-magnetic region corresponding to the masked region. 提供了由包含非磁性奥氏体成分的初始部件形成双相磁性部件的方法。该方法可以包括：在初始部件的一部分表面上形成涂层以形成掩蔽区域，同时在其上留下未掩蔽区域。此后，可将初始部件加热至处理温度，使得氮从初始部件的未掩蔽区域扩散出来以在未掩蔽区域中将非磁性奥氏体成分转变为磁性相。此后，可以将初始部件从处理温度冷却以形成双相磁性部件，该双相磁性部件具有对应于未掩蔽区域的磁性区域和对应于掩蔽区域的非磁性区域。
