Abstract

This invention relates to the coating of two incompatible but sliding surfaces with a thin layer of tough, wear-resistant material to prevent wear between the surfaces. More particularly, the armature and stator of a Linac slider can be coated with titanium nitride to prevent wear therebetween.

Ultra-Thin High Wear Life Coating for Linac Armature

      This invention relates to the coating of two incompatible but
sliding surfaces with a thin layer of tough, wear-resistant material
to prevent wear between the surfaces.  More particularly, the
armature and stator of a Linac slider can be coated with titanium
nitride to prevent wear therebetween.

      A hammer actuator assembly 1 is shown in the Figure and
comprises a stator 2 having stator face portion 3 positioned on top
of elongated slider 4 and its armature 5.  The stator 2 has stator
wear pads 6 that are positioned rectangularly across stator face
portion 3 proximate to slider armature 5. Armature wear pads 7 are
located rectangularly across slider armature 5 for allowing alignment
with stator wear pads 6. Another stator is positioned below slider
armature 5, but it was not illustrated nor specifically discussed
because its stator wear pads are aligned and operate in the same
manner with the armature wear pads attached on the bottom of slider
armature 5.

      In operation, slider armature 5 slides perpendicularly relative
to the position of stator 2 when an appropriate magnetic field is
applied by stator 2.  This sliding motion, however, results in
friction between armature wear pads 7 and stator wear pads 6 causing
the surfaces of armature 5 and stator face portion 3 to wear and
reduce the actual working life thereof.  To avoid this wear, a
titanium nitride coating of about two to three micr...
