Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
86 words
A method for coating a metallic roller with an abrasive, wear-resistant surface coating comprising the steps of: coating said roller with an innermost layer of molybdenum particles; flame spraying onto said innermost layer a first intermediate layer of stainless steel particles, a second intermediate layer of ceramic particles, and an outermost layer of stainless steel particles, said stainless steel particles being larger than said ceramic particles; and blending said molybdenum, stainless steel, and ceramic particles to form a composite molybdenum-ceramic-stainless steel core within said surface coating.
Claim 2
Independent Claim
86 words
A method for coating a metallic roller with an abrasive, wear-resistant surface coating comprising the steps of: coating said roller with an innermost layer of molybdenum particles; flame spraying onto said innermost layer a first intermediate layer of stainless steel particles, a second intermediate layer of ceramic particles, and an outermost layer of stainless steel particles, said stainless steel particles being larger than said ceramic particles; and blending said molybdenum, stainless steel, and ceramic particles to form a composite molybdenum-ceramic-stainless steel core within said surface coating.
Claim 3
Dependent Claim
69 words
A method as claimed in claim 1 wherein said innermost layer of molybdenum particles has a thickness of at least 0.003 inches, said first intermediate layer of stainless steel particles has a thickness of at least 0.005 inches, said second intermediate layer of ceramic particles has a thickness of at least 0.008 inches, and said outermost layer of stainless steel particles has a thickness of at least 0.003 inches.
Claim 4
Independent Claim
71 words
A method of covering a metallic roller comprising the steps of: coating said roller with molybdenum particles; flame spraying a first layer of stainless steel particles onto said molybdenum particles; and coating said first layer with ceramic particles, said stainless steel particles being larger than said ceramic particles, whereby said ceramic particles blend into said first layer of stainless steel particles to produce an abrasive, wear-resistant surface coating on said roller.
Claim 5
Independent Claim
71 words
A method of covering a metallic roller comprising the steps of: coating said roller with molybdenum particles; flame spraying a first layer of stainless steel particles onto said molybdenum particles; and coating said first layer with ceramic particles, said stainless steel particles being larger than said ceramic particles, whereby said ceramic particles blend into said first layer of stainless steel particles to produce an abrasive, wear-resistant surface coating on said roller.
Claim 6
Dependent Claim
35 words
A method as claimed in claim 3 further comprising the step of flame spraying a second layer of stainless steel particles onto said abrasive, wear-resistant surface coating, said second layer diffusing into said surface coating.
Claim 7
Dependent Claim
27 words
A method as claimed in claim 4 wherein said molybdenum particles blend into said surface coating to form a composite molybdenum-ceramic-stainless steel core within said surface coating.
Claim 8
Dependent Claim
18 words
A method as claimed in claim 3 wherein said ceramic particles are 45 to 70 microns in diameter.
Claim 9
Dependent Claim
19 words
A method as claimed in claim 6 wherein said stainless steel particles are 135 to 700 microns in diameter.
